When they jumped, they were heading towards an underground tunnel.

"Hang on!" Cat Noir says as he and Ladybug fall 50 feel down a whole.

The breeze blew through her face as she saw how extraordinary brave and handsome Cat Noir looked when the wind blew through his hair.
Then when they landed, they all stopped to see a very large gap between them and another tunnel.

"Now what?" Cat Noir asked.

"Look there's a handle over there." Ladybug pointed out. "Adrien could swing us over there?"

But Mommy Long Legs wasn't finished with them.

"Where did you go?"

They were all startled when they heard her voice.

"The game is over, you won."

They looked around to see where she was coming from.

"Come back and Mommy will give you the code, pinky promise."

"Sorry but we're getting off this crazy train and going to the real one that'll get us out of here." Ladybug says as Cat Noir uses the blue hand to grab onto the handle.

"But she has the code." Cat Noir says.

"She wasn't going to let us go, the games were just a subterfuge ruse to keep us here." Ladybug says as he started to put the pieces together.

"But what about the last code?" Cat Noir asked

"We'll just have to figure out how to start the train, now let's go." Ladybug answered.

They were moving fast, at the end of the tunnel was a dead end.

Then Ladybug noticed a hole up above then, Cat Noir pulls them up.

"Mommy knows the game is really hard."

Ladybug ignores her as they get out of here.

"But Mommy has decided that you won."

They then past by a poster: Mommy Long Legs and family.

"Come back" she laughs hysterically. Cat Noir shivers walks up the stairs.

"Mommy doesn't like cheaters!"

They walked through a hole in the wall and finds they have to pull themselves up again.

"The rules are so simple, COME BACK TO ME!" she then started to sound serious as it scared the two of them a bit.

Then there was a ventilation shaft, Ladybug and Cat Noir crawled in.

"UGH HOW DARE YOU DISOBEY ME?!"

"I will find you and when I do-" she starts to laugh hysterically as they crawled out.
"Where are you? WHERE ARE YOU?"

Then they look up to see another handle, Cat Noir uses the blue hand and pulls them up. They see a door but to find it is lock, so they walked up some stairs and it takes them to the water treatment.

On the panel, Cat Noir sees two buttons.

He presses the one that says route top 90 degrees and it forms a bridge above the water.

"Nice work Adrien." Ladybug says and they ran downstairs.

It takes them to another room, they sees a cutout of bee-cat in a bee hive. There was a button as Ladybug approached it, hits the button: meow meow meow, buzz!!!

They both looked at each other then Ladybug hits the button again: to bee or not to bee that is the question.

Cat Noir rolled his eyes at the lame joke and annoying cat's laugh. They then walked as Cat Noir sees a button far from him then he looks up and sees that there were colorful buttons above and around them. He looks down and sees two levers, he pulls the one of the right and they all got spooked when it pulled them down.

They then realized they were on a lift. It took them down to the last floor, where they walked across a bridge and found themselves crossing the other side of the water treatment where they walked in the other side. Walking back up, Cat Noir hits the top route button and the bridge moves to the left side. He keeps hitting it until he goes straight in the middle, where he runs off to join Ladybug as they cross the bridge to area that was marked C4.

There they saw a toy scanner, he pulls out a bunzo toy from earlier and puts it on the scanner once the scanner scans the toy, the doors opened.
But on the top of the doors it said: do not enter.

Looking around it was an empty room, then Ladybug finds a ventilation system again and they crawl through. They got out and it took them to a strange room, there was a yellow door and a large crack in the wall. So they left, going back to where they started but when they got black to the room with the cutout of the Boogie Bot, she presses the button: lets Bo-bo-boogie.

They went through the ventilation system. But then they fell and landed in a strange red room.
They looked around then Ladybug sees a hole in the ceiling as she looks and sees a handle, she turns around to get Cat Noir. Ladybug looks back and she makes the same face as she back up. They saw Mommy Long Legs screaming and land down in front of them.

Then Mommy Long Legs got really mad, "I ASKED YOU TO PLAY FAIR, AND YOU CHEATED!"

They try to back away from her in fear.

"I HATE CHEATERS, now we're going to play ONE LAST GAME!"

"It's called hide and SEEK!!!"

As they back up to a gate, Mommy Long Legs started counting backwards.

"10...9-"

Then the door opened and they quickly ran.

"7...6"

They ran downstairs, jumping over a big gap.

"5...4..."

They then made it down a strange and broken room.

"3...2...1"

They ran, they didn't know but it was somewhere far from Mommy Long Legs. They climbed up the stairs and crawled through a small hole. Running in the dark wasn't easy, especially when it's hiding form a very big and dangerous spider-like toy. They crawled through a tunnel, jumped through a vent that was heading down. Ladybug then sees a lever, she pulls it and a small door opens, they went inside.

They wandered around in the building until they were in bay 2. They're were four levers on the wall, a red, green, blue and yellow one.

"Come on, start pulling some levers." Ladybug says as he pulls the red one.

They started to pull the levers, then the gate opened, they ran in and looked around, staying alert for Mommy Long Legs. Then all of a sudden, they heard noises, it was Mommy Long Legs.

"Ah!" Ladybug screamed.

She was laughing hysterically.

"Run!" he says as they ran from Mommy Long Legs.

Then Cat Noir pulled them up as they saw Mommy Long Legs, crawling and looking for them. Then they landed down when they heard her gone. They ran back to where she chased them, found another room, with a gate and a lever. Cat Noir then finds a power charger and receiver, he grabs them both and behind them a furnace lite up. Cat Noir walked up the stairs to see a piece missing, he found the missing piece and puts it back in. Apparently it made an extra wheel but Ladybug made a realization.

"Adrien, get the wheel!" She told him.

So Cat Noir grabs the yellow wheel and puts it in the machine near the lever, and Ladybug pulls the lever again. And it opens the gate, they ran in, they suddenly Mommy appeared.

"Quickly, back to the furnace!" Ladybug says.

As they got inside, Ladybug shuts the door, they heard Mommy crawling around looking for them. Ladybug signals to Cat Noir to keep quiet. They heard something dropped, Ladybug slowly opened the door and saw she was gone.

So they ran through the door, going in a room filled with spiderwebs. There was another lever, Ladybug pulls it then when they felt going down, they heard Mommy Long Legs, so they ran again, but this time they were going to finish her.

So they ran out of the room, jumping over gaps, running through the sewers, Cat Noir pulls them up. They then made it to a well lite room with a painting of Mommy Long Legs, above her door was a hand scanner. Cat Noir uses the blue hand, they were waiting anxiously to for the door to open as they heard mommy getting closer.

"Come on hurry!" Ladybug said.

Then it opened as they saw her getting closer then Cat Noir gets upset.

"That's it I had enough of this." Cat Noir said as he was going up to a grinder, grabbing a lever.

"Adrien, what are you doing?" Ladybug asked.

"Ending this game once and for all!" Cat Noir said.

She were confused at first but then they heard Mommy Long Legs coming in, they all backed away as she stared at them.

But as she tries to go up to them, her hand was caught in the grinder. Then Cat Noir pulls the lever and she slowly gets reeled in.

Mommy proceeds to howl in horror and pain and screams.

"WHAT HAVE YOU DONE?! HE'LL MAKE ME PART OF HIM!!!"

Cat Noir jumped down to watch her die as Ladybug moves over to him, she clings onto him looking at him then back at mommy long legs.

"YOU CAN'T DO THIS TO ME!!!"

But her attempts to free herself are futile as she continues to claw on the floor. When the grinder crushes her abdomen, splattering the grinder with blood.

Ladybug buried her face in Cat Noir's chest as he wraps his arm around her, cupping her head.
Her torso then severs from her chest and collapses to the ground, and they all surrounded Mommy Long Legs.

"Well it's over now." Cat Noir says.

Suddenly, a mechanical claw slowly appeared and dragged Mommy Long Legs.

"Uhh... Adrien, what was that?" Ladybug asked.

"I have no idea. But I suggest we get going." Cat Noir said as they de-transform.

The gate behind them opens up as they headed off.
