Time for a Doctor!

A Doctor Who/Adventure Time crossover that I thought I'd never get to do. Hope its good!

Chapter 5: Ooo's mission

"Aha.. we are on the moon!" The Doctor says stepping from his TARDIS followed by Jake and Finn.
"How?" Jake asks floating past the Doctor.
"How the breathing or how are we on the moon?" the Doctor asks picking up some dust from the moon's surface.
"Both!" Finn says jumping off from the moon.
"Well the TARDIS moves in space and time so we can be anywhere in Ooo's time line and the breathing... I don't know!" the Doctor says tasting the moon's dust.
"So when are we?" Jake asks morphing into a yellow copy of the Doctor with out the trench coat.
"Good question... I dont know!" the Doctor says as P.B stummbles from the TARDIS.
"We are on the moon!" P.B says with wide eyes.
"We are!" the Doctor says grinning.
"We can't be here!" P.B says walking back into the TARDIS.
"Why?" the Doctor asks.
"No no.. how's this possible!" P.B says running her fingers through her Bubblegum hair.
"Why.. why can't we be here!" the Doctor asks.
"P.B what's wrong?" Finn asks as the TARDIS is rocked.
"O...kay!" Jake says confused closing the doors behind him.
"No no.. we must leave!" P.B says slumping down into ball.
"Why.. what is wrong?" the Doctor asks.
"Oh... no!" the Doctor adds running towards the TARDIS controls.
"What's wrong?" Finn asks.
"The moon.. this moon is not the moon of Ooo is it?" the Doctor asks turning to P.B.
"It is.. or it will be!" P.B says as the TARDIS is rocked again.
"What is going on?" Jake asks.
"Millions of rockets are going on.. a young P.B and her father.. maybe a kind King worried for his people is protecting his people!" the Doctor says making P.B stand up.
"I'm correct right... the rockets are incressing the gravity of this moon!" the Doctor says getting a nod from P.B.
"Why?" the Doctor asks.
"Oh.. I'm so stupid.. stupid Doctor!" the Doctor adds.
"Your not striking the moon itself.. your attacking the gravity.. because.. because it's killing Ooo!" the Doctor says getting another nod from P.B.
"When are we?" the Doctor asks.
"The Gumball war's... over 14 years ago!" P.B says.
"Why?" Jake asks.
"The gravity.. it's pulling Ooo apart.. when P.B was 6 she saw the fall of Ooo.. her home getting killed by the moon she loves... the moon she wanted to visit!" the Doctor says getting a nod from P.B again.
"So what's going to happen?" Finn asks.
"Gravity clusters!" P.B says.
"A rocket you and your father built.. it's incressing the gravity around the moon.. insted of the moon pulling Ooo.. it will.. in theory kill the extra gravity." the Doctor says flipping some levers on the console.
"How do you know all this?" P.B asks.
"I'm the Doctor.. the last of my kind.. and I guessed!" the Doctor says flipping the last lever, the TARDIS humms and vanishes from the moon just as the last rocket was going to hit.

"Where are we now?" P.B asks stepping from the TARDIS into the sunshine.
"Ooo.. same time.. just on the outskirts of the Candy Kingdom!" the Doctor says running his fingers through his hair as Finn walks out.
"Why?" Jake asks falling out of the TARDIS.
"Watch!" the Doctor says pointing towards the last rocket heading for the moon.
"I thought me and my father were doing the right thing!" P.B says closing her eyes.
"You know... Gravity Clusters are tricky things to work with.. sometimes they miss!" the Doctor says watching the rocket miss the moon but strike a metor sending it towards the moon.. where it strikes the moon spinning it further away.
"I think that's what they call a backspin!" the Doctor says nudging P.B who opened her eyes to watch.
"You planed that?" P.B asks.
"Of course.. you were young at the time.. your father was worried that he failed.. so I changed history!" the Doctor says.
"The war.. it never happend?" P.B ask a grinning Doctor.
"Who can tell.. all I know is I saved another world from doing something horrible!" the Doctor says walking back into his TARDIS.
"You coming?" the Doctor adds sticking his head from the TARDIS door's.
"Yeah!" Jake and Finn say at the same time followed by P.B, the hum of the TARDIS welcoming her back in.
