1. Scarab's Wish

Prismo was instructing Scarab how to grant wishes, now that they were both wishmasters. "Can I have a wish?" asked Scarab. "Why do you ask?" asked Prismo. "I want a sandwich." said Scarab. "Ah, Scrabby, I can't tell you how many times people have asked that question, and you've heard me answer it! I can just make you a sandwich!" said Prismo. "Please do." said Scarab. "Alright." said Prismo, going to make Scarab a sandwich. "With Prismo gone, I can do what needs to be done!" said Scarab, with a mischievous grin, "I wish to be the only wishmaster!" said Scarab, as he granted his own wish.

Later on, Prismo fell through a portal in Fionna and Cake's roof, screaming, with a half-prepared sub in his hand... as a human? Cake stretched and caught Prismo. "You look... familiar!" said Cake. Prismo looked at himself. "At least I don't look old as a human anymore! Oh, hey Fionna and Cake! I'm in your apartment!" said Prismo. "Fionna! A guy with pink hair fell through a portal in the roof!" hollered Cake. "Coming!" shouted Fionna. "Hey Fionna!" said Prismo. Fionna dropped her water bottle. "Is that you, Prismo?" said Fionna. "Yes." said Prismo.

"Since when were you a human?" asked Cake. "Maybe... 5 minutes ago?" replied Prismo. "Tell me how, Prismo!" said Fionna. "Well, Scarab dec-" said Prismo, as Cake interrupted, cutting Prismo off, "May I have that half of a sandwich?" "Sure," replied Prismo. "Ok, what about Scarab?" said Fionna. "While I was gone making him the sandwich that Cake is eating right now, he backstabbed me and wished to be the only wishmaster, and granted the wish by himself, I know, I shouldn't have taught him how. So, he wished, and I was teleported here." explained Prismo.

"Well, can't you wish to be wishmaster again?" asked Cake. "Well, I don't know how to make it to the Time Room from this universe without the remote." said Prismo. "Can't you grant your own wish?" asked Fionna. "Nope. Only wishmasters can." replied Prismo. Cake shapeshifted like Prismo's old form. "How about now?" asked Cake. They all laughed. "As your creator, I didn't even know how good of a sense of humor you have." said Prismo. "So? How does this world work?" asked Prismo. "The total opposite of how you planned it." said Fionna.
