Caillou walks out of the house with his friends in costumes.

Caillou: Where should we go first?
Leo: I know! Mr. Hinkle's house.

Cut to Mr. Hinkle's house.

Caillou+Leo+Clementine+Jason+Jeffrey+Xavier+Emma: Trick or treat!
Mr. Hinkle: What wonderful costumes! Here's some treats for y'all.

Caillou and his friends go all over the neighborhood and get some treats.

Cut to Caillou's house.

Boris: How dare you go trick or treating! You're grounded until next year! Go to your room right now! And don't eat any of those treats!

Caillou cries and runs to his room. Boris eats all of Caillou's Halloween candy until he becomes fat.

The End!!!!
