(I think I have a plan.)
Wilburt Sandex is known to be an evil magician. He applies his knowledge for no good.
Once, he invented chocolate raisins that would make you sleep for 500,000 years if you ate any. Of course, this means numerous time periods, but not as long as the next continental drift. Sandex also had a soft spot in his heart and designed the Magic Oud, the only thing that could break the spell and wake the victim, but he hid the Oud.
Later, Sandex also invented swiss cheese that would result in you having a 104-degree fever if you ate it. But since people already know how to deal with fevers, he didn't design anything extra, even though he tested the material on his brother, Salidge Dmitri Sandex.
Finally, in 2017, Sandex came out with evil falafel. If two people eat this falafel together, they will switch bodies... and this spell will last for 1,024 years unless hot sauce is dumped on both bodies.
Unikitty: Ahh... isn't the kingdom so joyous!
Gumball: Yup, Elmore sure is--wait, what are those?
Unikitty and Gumball come across a table with chocolate raisins, swiss cheese, and falafel. But no one is serving the food
(Oh, sorry about~ I guess this one will start a bit differently)
Unikitty: Can you believe... we're going... to the Space Needle? Oh, I'm so excited!
Puppycorn: Yeah! I heard they have games, and awesome tricks...
Gumball: Okay, calm the excitement... we should focus on being fully packed first.
Darwin: Yup, that's why I'm too busy packing to talk to you guys! Wait... did I just talk?
