(Hey guys! Remember that incident Merlin mentioned about messing with time in a very early chapter..?) 

"Ahhh.. yes!" Merlin appeared in Academy City in a burst of shifting light, dusting himself off. "Finally I have succeeded in recreating that time travel experiment I had started a few years ago!! First I have managed to go to the past.. and study the fauna known as Dinosaurs.. and now I have managed to travel to the future where my darling King is the Servant of that Misaka girl... wait.. WHAT IN THE WORLD!!!!?"

Merlin stared in shock.. everyone around him.. were APES AND MONKEYS!!

Lemurs in Tokiwadai uniforms.. chimpanzees in school blazers..

Even  Orangatans in cross guard uniforms were there directing traffic!!

The Windowless building was now shaped like a giant banana.. and giant statues of monkeys clapping symbols were standing tall around the city.. the name of which now read on a sign "Ape-Cademy City."

"WHAT THE HELL!?" stammered Merlin.

"MERRRRLINNN YOU IDIOT!!!" Twilight Prankster appeared in a burst of smoke in confetti. "AGAIN MERLIN!? REALLY!? HOW MANY TIMES DO I HAVE TO TELL YOU!? If ya go to the past and give the monkey a donut.. YOU END UP WITH MONKEYS RULING THE FUTURE!!!!! This is the second friggin time you dope ass!!!!"

"I'm sorry.. " Muttered Merlin. 

"SORRY DOESN'T EVEN BEGIN TO CUT IT!! When I decided to take you on as my magic apprentice when you first started out.. didn't I say that even trolling had a time and place!? Now look at this place.. THAT SCHOOL BUS IS A GIANT BANANA ON WHEEELS!!"  Prankster roared. "HELL!! LOOK!! THERE'S EVEN A SABER BABOON!!!"

"AGGGHH AGGGGHH!!" A baboon wearing Saber's outfit screeched, waving Excalibur wildly with one arm.

"I think you're blowing this out of proportion here." stammered Merlin.

At that moment.. multiple Anti-Skill vehicles pulled in.. and Gorillas in tactical uniforms, carrying Banana shaped Guns, came out.. pointing their weapons at Merlin. 

"Oooh ooo ooo!!" said one Gorilla, which in English, means " We've got another one that escaped from the Human Zoo.."

"A HUMAN ZOO MERLIN!!! A HUMAN ZOO!!! YOU THINK I'M BLOWING THIS OUT OF PROPORTION!?" Prankster screamed. 

"Alright alright!!!"  said Merlin.  "But... how do we fix this?"

"Well.. It ain't gonna be easy.. there's only one way to solve a problem like this." said Prankster. "With a good old fashioned kid's cartoon.. OH MISSS FRRRIIIZZZLEEEEE!!!!!"

Suddenly a giant yellow school bus appeared with eyes for headlights and a mouth for a bumper.. and a door opened to reveal a frizzy haired teacher waving with a bunch of kids in back. "OHHH PRANKSTER! Hello again!!"

"TIME FOR THE MAGIC SCHOOL BUS!!!" Prankster yelled giddilly, throwing Merlin into the bus and jumping in himself.

"Oh please let this be a normal field trip!" said A boy with glasses nervously.

"WITH THE FRIZZ ARNOLD!? No way!!" Said Prankster.  "TAKE IT AWAY CRAZY TEACHER WHO SOMEHOW NEVER DRAWS ATTENTION TO HERSELF WITH THE BUS THAT HAS AN ACTUAL FACE AND FOR SOME REASON NEVER EXPLAINS WHY THE SCHOOL BUS IS MAGIC IN THE FIRST PLACE!!"

"Alright kids!! Ready  to journey back to Ancient Camelot to meet King Arthur!?" said Ms. Frizzle with glee.

"And don't worry kids! Thanks to the Legal Documents you all signed.. we won't be held responsible if you all happen to be eaten by dragons, crushed by trolls, or if Arnold is stabbed by Mordred!!" said Prankster.

"Why would Mordred stab me!?" stammered Arnold.

"Arnold.." said Prankster with a sigh.. "EVERYONE wants to stab you.."

With that.. the Magic School Bus dissapeared in a burst of light.. leaving many readers shaking their heads just begging me to come out with the 4th book already... 

The... End?..
