Like I said Sonar does not belong to me but here we go! Sorry if this part is bad.

Sonar was wondering around on Mt. Ebott when SUDDENLY she fell down a hole. Surprisingly she wasn't hurt due to landing on a bed of golden flowers. Buttercups from what she knew they were called. Sonar wondered again until she came across a buttercup that happened to have a face on it. "Howdy! I'm Flowey, Flowey the flower" Flowey said. Sonar trusted the flower with him helping her know the rules but wanted to play around and dodged the white pellets all 3 times. "You know what's going on here don't you? You just wanted to see me suffer!" said Flowey is a slightly demonic tone. Then pellets surrounded Sonar and Flowey said "DIE!" In a fully demonic tone.

Once the pellets nearly hit Sonar they disappeared. "W-what?" Flowey said confused. After a few seconds Flowey was hit by a fire ball and knocked away and with that a goat lady came. "Ah. Do not be afraid my child. I am Toriel care taker of the Ruins." said the goat lady now known as Toriel. Sonar knew to trust her and followed her. Once Toriel left Sonar alone, Sonar decided to explore the Ruins after a while she found Toriel's home but Sonar on her way there spared everything. Toriel was surprised to see Sonar was there and unharmed. Toriel was making butterscotch cinnamon pie at the time and after Sonar had slept and woke up she seen Toriel had left her some pie on the floor. Sonar saved the pie for later and went to talk to Toriel. "Toriel c-can I go explore outside" Sonar asked shyly.(this is where it's not like the game) "Yes you may my child but please be careful and come back soon the way out of the Ruins is down stairs at the end of the hall." Toriel said while smiling. "Thanks Toriel!" Sonar said while walking to the basement. Once at the door Sonar took a deep breath and opened the door.

Sonar found herself wondering on a snowy path in cold weather. But she wasn't cold due to being a kitsune.(pronounced:kit-sun-A) A kitsune is an artic fox in japenese mythology. So Sonar had her fur to keep her warm in cold weather. Anyway back to the story. Sonar soon came across a bridge with a fence like thing on it but the bars were too wide to stop anyone but then Sonar heard someone walk up behind her. "Human....don't you know how to greet a new pal?.......turn around and shake my hand." Sonar did as told and a far noise was heard. "Whoopee cushion in the hand trick always funny....Hey you're not human are you. Funny. I'm Sans, Sans the skeleton. I'm sorta supposed to keep watch for humans and kitsune but not in the mood for capturing people bu-" Then a yell was heard.  "SANS WHY ARE YOU WITH A KITSUNE!" "Sorry no time to talk just take my hand quickly!* Sonar trusted Sans and took his hand and in a split second they were in a restaurant. "Welcome to Grillby's" said Sans to Sonar. "Alright but who was that who yelled at you?" "That was my bro Papyrus like I was about to say he hates kitsune due to past meetings with them." "Alright well what do we do now?" said Sonar confused on what to do. "Want anything to eat?" Sans asked. "Sure why not" The two sat at the counter and ordered some burgers. "So kiddo where do you live?" Sans asked. Sonar replied with "I live in the Ruins" "Oh ok kid." Sans said.

As time passed Papyrus got used to Sonar being around his brother, Sans and it had only been a few weeks for Papyrus to get used to it. That day Sans told Sonar to meet him in the wishing room in water fall. Once Sonar got there she seen Sans there waiting for her. "Sonar you made it!" Sans said excited. "Yea I made what did you wanna see me for?" Sonar asked. Sans replied with, "Knock knock" "Who's there?" Sonar said going along with the knock knock joke though she didn't know what was coming to her. "Will" "Will who?" Sans replied with, "Will you be my girlfriend?" Sonar blushed a little and she nodded. The two hugged and lived happily ever after once Papyrus got used to them being a couple. THE END!
