"So, this is the Wishing Cave? It's so cool! The glowing rocks on the ceiling! They look exactly like the actual stars almost!" Lily said as she looked at the twinkling stones. Sonic nodded in agreement.

Shadow had caught up to them and the echo flower still haunted him in his mind. However, he knew that by thinking about it, he was simply inviting negative thoughts. The Wishing Cave did look like the night sky. It put him at ease.

As they made their way through the darkness, they could hear the echo flowers repeating more hopes and more wishes. One echo flower stood out more than the others. It sat in the middle of the road and spoke a little louder than the rest. The voice was familiar. A good kind of familiar.

"Check the wall," it told them in a deep, male voice. They all heard the voice before. Lily was about to say who she thought it was, but it got the better of her.

"Check the wall. What wall?" asked Sonic as he looked around.

"Maybe this dead end wall over here? It really looks like there should be a door over here," Shadow stated as he pointed to the wall. They all approached the wall and touched the hard rock. The rock wall then formed a door. Sonic nodded to Shadow and they proceeded.

They came to a room full of lit up signs. As they each read the signs, they realized that it was the story of how they were sealed underground by the humans. Sonic suddenly realized that it wasn't completely true NOW because Shadow had sealed them all underground with the chaos emeralds. However, he was sure that the other parts were true. As he looked at one of the signs, one of them had a picture of a bizarre monster on the front of it. Something about it disturbed him. He moved on after looking at the picture for a long while.

The next room was dark and was only lit by the little light that came from behind them that caused for long shadows to stretch across the ground. There was something unsettling about this. The Waterfall was an unsettling place in general. They felt like they were being watched...

CRASH!!!!

A blue, electrical spear pierced the ground just in front of them! Sonic and Lily nearly screamed and Shadow jumped. Sonic saw Undyne a little ways away lobbing spears in their directions. They began to run.

"Sonic, why didn't you warn us about the electrical spears! You saw that she had one! Why didn't you say something?!" demanded Lily as she ran.

"Maybe I thought it wasn't important!" Sonic yelled in reply.

"Well, it was!" Shadow retorted.

Crash! Crash! POW!!

They could see more tall grass just ahead of them. Sonic hoped and prayed that the tall grass would hide them just as well as last time. He grabbed onto the wrists of Shadow and Lily and to the grass they dove once again.

Undyne came storming through the grass and searched around. She was now standing right in front of them and she grabbed down on someone! She pulled up the being who she had caught...

A grinning dinosaur kid was in her hand. She stopped for an awkward second and slowly put Dino Kid back into the grass. She retreated back the way she had come. The three hedgehogs sighed to themselves.

They walked out of the tall grass and Dino Kid was coming out with them. He jumped excitedly. "Did you see that?! Undyne just-TOUCHED ME!! I'm never going to wash my face ever again! Man! You three must be very unlucky. Imagine what would have happened if you were just a little bit to the left... Let's go! We can't let Undyne get away from us!" With that, Dino Kid ran off leaving the three hedgehogs to wonder what just happened.

They found a save station in the next room. After saving and continuing, they found Sans standing next to a telescope. He looked asleep for a moment, but then opened his eyes when the hedgehogs approached. He closed them again as if he was hardly interested. Lily knew he had something up his sleeve. She didn't even know how he got there. He must've known that they would get there eventually.

"Huh. I wonder what Sans wants," Sonic commented.

"You know, I'm thinking about getting a job with a telescope company. You three wanna be my first customers? It's free," Sans explained. He was obviously hiding something. He was avoiding eye contact with Shadow and was sort of messing with something in his pocket. Lily was too curious to resist.

"Well, I thought that you already have two jobs? The more the, uh, merrier..., maybe...? I'll be the first to try your telescope, though!" she said trying not to phrase the sentence wrong.

Sans side stepped and she looked through it. She let out a long, annoyed sigh and stood up. She turned and looked to Sans. Sans put pink paint on the eye lense making her eye appear pink! She growled at Sans who burst into laughter.

"You're evil sometimes! EVIL!!" Lily yelled at Sans. She scowled at Sonic and Shadow who were also trying their best not to laugh.

"Oh? You're not satisfied? It's ok. I'll give you a full refund!" Sans told her with a wink. However, there was no money to pay back because it was free! Everybody was laughing now except for Lily. She continued to look at Sans with a really ticked off look on her face.

"Let's just keep moving..."

They walked a lot further and read more signs. There were more echo flowers which only freaked out Shadow even more. They ran into a guy named Unionsan and got attacked by Undyne again! She explained to them how they only needed three more animal souls before they could reach the surface. She bashed the ground out from under them and they were sent falling! Down... down... down...

CRASH!!

"Oh man... Shadow, Lily, are you two okay?" asked Sonic as he sat up from the long fall. A bunch of yellow flowers broke his fall. He sighed with relief. Lily and Shadow nod to answer his question.

"Yeah, we're fine. However, where are we? What is this place?" asked Shadow as he looked around at all the trash.

"Looks like a trash dump," Lily answered as she glanced around.

They found another save point and saved before they kept going. There was a bunch of trash lying around. CDs for an anime..., a bike..., and there was also a dummy! A training dummy! Sonic walked up to it. He didn't touch the dummy. Lily just walked past it without even acknowledging it. Shadow punched the training dummy. He felt... Shadow kept on walking as he tried not to think about the way he felt. Right as they were about to leave the trash dump, though...

The dummy jumped in front of them with an angry expression on its face. It was a mad dummy! Sonic, Shadow, and Lily all shouted in unison.

"You foolish brats! The blue hedgehog just thought he could stare me down to annoy me! The little girl just thought she could just completely ignore me, did she?!?!? Then, there's you!!! You, black hedgehog, you punched me without considering the possibility that you might be hurting someone. I don't know what you think, but you are a very hurtful person!!!" the mad dummy screamed.

"Whoa, whoa, whoa! Chill for a minute! Whatever we did to offend you, we're sorry for doing it! We just want to pass safely and leave the trash dump to reach the exit to the Underground and hopefully break the barrier!" Sonic explained.

"Wait a second... You're that hedgehog from the ruins! My cousin was the dummy from the ruins and you just chattered on and on just boring my poor cousin to death with your nonsense! Do you know how long it took for him to become corporeal?!? Well, you all don't deserve to live after what you did to my cousin!!" screamed the mad dummy. The mad dummy turned into a bright red and they went into battle mode.

They tried to talk and Shadow once tried to attack, but nothing worked. The dummy was incorporeal and wouldn't listen to their words. It attacked them with its magical attacks and Lily got an idea! She whispered to Sonic who nodded.

"Hey you DUMMY, come a get me if you can!!!" Sonic yelled. The dummy glared at the hedgehog and launched a dozen of magical attacks at Sonic. Sonic ran around in a circle and sent them soaring towards the mad dummy! The dummy couldn't get away in time! The attacks hit the dummy and he yelled in pain.

"YOU!!!! GrRrRrRr... These magical attacks are just useless! USELESS!!! I'll just attack you with more advanced attacks!!" the mad dummy screamed.

Shadow did the exact same thing Sonic did and it worked again! The attacks hit the mad dummy and the dummy was hopping around and screaming insults towards them. Lily was feeling a little sorry for it because some of its stuffing was coming out.

"MAN!! THESE ARE WORSE THAN THE LAST ATTACKS!! I'll just use knives!" yelled the dummy as it threw a knife towards Shadow who sidestepped before it hit him. The knife fell on the ground. The mad dummy stopped. "I'm out of knives... WELL, I DON'T NEED KNIVES!!! ALL YOU FOOLISH PEOPLE HAD BETTER DIE THIS INSTANT SO I CAN TAKE YOUR SOULS TO CROSS THE BARRIER AND TO AVENGE MY COUSIN!!!" screamed the dummy.

Sonic, Shadow, and Lily were about to face another attack from the mad dummy when something interesting happened. It started raining. ACID rain. It rained all over the dummy. The mad dummy yelled and looked up to see Napstablook raining all over it.

"ACID RAIN!?!?! AHHHH!!! Oh whatever!! I'm outta here!!" yelled the dummy as it ran away.

Sonic waved to his friend Napstablook. "Hey, Napstablook! How's it going?!"

"Oh... I'm terribly sorry for making him go away... You looked like the four of you were having fun, too... Oh...," wept Napstablook as he sort of faded away. He reappeared a few feet away and looked back to them. "Oh, my house is just up ahead if you wanna come visit... Then again... You don't have to... It was just a friendly suggestion... Uh- Nevermind..." Napstablook then disappeared.

"Wait!" called Lily as she reached her hand out, but the ghost was already gone. She sighed and looked to Sonic and Shadow. "Let's go visit. He looks like he could use a pick-me-up."

Sonic and Shadow nodded in agreement as they made their way out of the trash dump. They came to a clearing that had five ways to go. One way headed to the little bird that would carry them over a disproportionately small gap, one to a fish house, one to Napstablook's house, one to continue forward, and one to Napstablook's family business.

The three hedgehogs visited with Napstablook and listened to his... unique soundtracks. They tried to get snacks, but there were only ghost snacks. They also tried the snail race. Somehow, Sonic would always turn his snail into a flaming inferno by encouraging it too much! Lily would always win and Shadow would lose because he wouldn't encourage it at all. Napstablook still made money, though! His mood seemed to have improved a bit!

After hanging out with Napstablook for a bit, they finally said their goodbyes and left to continue forward. There were many dark rooms ahead and they had to light these little crystals to see where they were going. While they were wandering around in the dark, they stumbled across a tiny village that were full of... cats? I'm sorry, what are they again?

"hOI! I'm Tem! Tem da Temmie! Dis is Tem Village! Evewy Tem say hOI!!" announced a Temmie to its buds. The entire village turned to the three hedgehogs.

"hOI!!!!!!!!!!!" all of the Tem screamed all at once. It was chaos after that.

"What the heck is this place?" asked Shadow as he looked around.

"I have no idea...," Sonic replied as a Temmie tried to climb up his leg to say hOI. Sonic shook it off and it began to cry. Sonic instantly picked it back up again and it began to start babbling about itself and all of its friends with a huge grin.

Sonic turned around and started backing out slowly. However a bunch of Temmie with evil grins stood in his way.

"Meanie hedhog stay an pay 4 colleg or die!" they all yelled.

Sonic instantly got out his wallet and turned it upside down. The Temmie gathered around the one gold coin that fell from it and Sonic laughed awkwardly. "We're broke."

The Temmie then began to cry in unison. While the Temmie were distracted, Sonic grabbed onto Lily and Shadow and they ran away to safety. They were never going to come back...

Thankfully, nobody was harmed after they left the horrible Temmie Village. They looked back and sighed. After agreeing to never go back to the horrible place, they continued. Dino Kid walked up to them again. He wasn't grinning as much as he was the last time they saw him.

"Yo, I know I'm not supposed to be here, but I wanna ask you three something... Man, I've never had to ask anyone this before... Are you three hedgehogs from the outside?" asked Dino Kid curiously.

The three hedgehogs nod.

"Wow! I knew it! Well, I know it now, I mean... Undyne told me to stay away from the hedgehogs, so, um..., does that make us enemies or something?" asked Dino Kid.

"We don't have to be! We could be friends! I don't really wanna be your enemy," Sonic said to the Dino Kid.

"R-Really? Gee..., I was going to ask if you could insult me so I could have a reason to hate you, but I guess we'll just have to settle with being friends!" Dino Kid answered enthusiastically.

Sonic and Lily both grinned. However, their happy meeting was cut short when Undyne approached them. Dino Kid gasped and ran towards Undyne excitedly.

"Undyne! Look! I made friends with the hedgehogs! I knew that they weren't me- AH!!" yelled Dino Kid as he slipped and fell onto a mud slide. He was slowly falling down and couldn't pull himself up! He didn't have any arms! Sonic gasped and Undyne slowly approached. She was obviously cautious of Sonic.

Rather than doing nothing, Sonic ran up to Dino Kid. He helped him back onto solid ground and Dino Kid sighed with relief. Then, the young monster turned towards Undyne boldly. "If you plan on attacking my friend, you'll have to get through me!"

Undyne took a surprised step back. She looked around and then retreated away back the way she came unable to do anything. Dino Kid sighed and turned back to Sonic, Shadow, and Lily.

"She's gone... My parents must be really worried about me. How about we talk later! It was nice meeting you all!" Dino Kid said as he began to scurry away. Sonic and Lily waved. Shadow just stood and watched the sticky dinosaur run away. He still wanted to tip him over just to laugh at the fact that he had no arms.

Sonic turned to Lily and Shadow. "I can see an orangish glow coming from over there! I think that's the exit of the cave!" He pointed to the large door that lead to the next room.

"Let's go. We need to get out of Waterfall. Undyne will still catch us if we stay here too long," Shadow told Sonic.

"Right! C'mon guys!" Sonic cheered as he pointed to the light.

They walked through the door and they saw that Undyne had already beaten them to it. She was standing heroically on top of a giant mountain. She looked down upon the three hedgehogs.

"Four... That's how many souls we have... We just need three more before we can break open the barrier... Just like everyone else who passes through here, I'll tell you our tragic story...," Undyne told them. She stopped. She growled to the world. "WHY SHOULD I TELL YOU THAT STORY WHEN YOU'RE ABOUT TO DIE?!?!? PREPARE YOURSELF!!" she yelled as she yanked off her helmet.

"Wait a minute...," Shadow said.

"She's a-?!" Lily continued.

"She's a fish lady?!" finished Sonic trying not to laugh.

"SHUT UP HEDGEHOGS!! Come forward when you are ready to battle me!!" screamed Undyne as she raised a spear at them.

Sonic looked over and saw a save point. The three of them touched it and then they continued. As the three of them stepped forward, Undyne's grin only became bigger. She jumped down from the mountain and landed in front of them.

"That's right! No more running away! Prepare to DIE!!!" she howled as they went into battle mode.

She threw a spear at them and Shadow caught it. She grinned. "Use that to defend yourselves. You must learn that in order to accomplish the most difficult challenges, you need to face danger head on!" she yelled as she threw three spears at them. Shadow expertly used the spear as a shield and reflect the spears. Sonic began to panic.

"What do we do?! What do we do?! Is there a way to stop her?!" he demanded.

"You know, I know this gal named Zaira. She acts almost exactly like Undyne. I've battled her once before and I know the only way to beat her!" Shadow said.

"Wait... You know how to stop her?" asked Lily with amazement.

"Well, from the way I see it, the only way to beat her is to...," Shadow threw his spear on the ground and yelled, "RUN FOR YOUR LIVES!!!"

Sonic and Lily didn't wait for a moment. They fled after Shadow with Undyne hard on their tails. She was yelling at them and they didn't care. They were running so fast that they hardly realized that their phone was ringing. Shadow picked it up. "Yes?"

Undyne stopped. "Wait, who's that?"

"It's Papyrus," Shadow answered.

"Hello Shadow! I was just thinking that you, Sonic, and Lily should totally get together with Undyne sometime! I'm sure that the four of you can become friends! It's settled then! All of you shall report to her house as soon as you're able! Okay! That was all! Bye!" Papyrus finished.

"Hey Undyne, are you open for this afternoon?" asked Shadow.

"WHY DO YOU CARE?!!?!" she demanded.

"I'll take that as a yes. Where were we? Oh, yeah. RUUUUUUUN!!!!"

Sonic, Lily, and Shadow continued to run. They ran past a sign that read: Welcome to Hotland!! They raced into a place that looked like it was inside of a volcano. It was smoldering hot! Undyne began to slow down. They ran past Sans who was at one of his hotdog stands, sleeping. Undyne stopped in front of it and looked like she was going to yell for him to wake up, but decided it wasn't worth it.

They ran across a long bridge that sat above a large pit of lava. Once on the other side, they watched Undyne stumble her way across the bridge. She looked a little dried out... She growled at the hedgehogs. "Armor... So hot... Can't... give up... Not yet...," she said before collapsing on the ground and landing on her face.

"Oh-no!!" Sonic yelled as he raced over to her. Her scales were dry... Lily turned around and saw a water cooler. She ran over to it and grabbed a cup of water. She poured the water onto Undyne's scales and Undyne began to recover as she cooled off.

"Undyne! Are you okay?" asked Lily.

The warrior stumbled to her feet and looked at Lily and Sonic who were looking up at her with worried eyes.

"I-I'm... fine...," Undyne said. She turned around and walked away not responding when they begged her to come back. She was gone and no longer in pursuit of them.

Sonic turned and wondered why Shadow hadn't done anything to try to help Undyne. He saw Shadow emptying the water cooler and making a huge puddle on the ground. He grinned when he finally emptied out the whole thing. Was there something wrong with Shadow or was he slowly becoming more... evil?
