Danny Phantom

At the Amity Park Swap Meet, a wish-granting ghost named Desiree gets loose and grants a little girl her wish for cotton candy. Danny leaves Tucker to fight Desiree in the piles of cotton candy. He gets rid of her, but not for long.

Later, at a Casper High football game, Danny is stuck wearing the mascot suit. Dash, the bully/quarterback, wishes he could turn into a type of monster that could win the game single-handedly, and Desiree turns him into a Hulk-like Monster. Danny goes ghost to get the monster out of Dash, then releases him in the ghost portal, leaving Tucker to be the mascot.

Danny and Tucker are at a movie theater, where Paulina wishes she was more like a famous cartoon character to be more popular. Desiree grants her wish. Danny leaves Tucker, again, to go fight Paulina. In the theater, Tucker wishes he had ghost powers like Danny. Desiree happens to hear that wish and grants it for him. Tucker, wanting to have fun, messes with people's heads by doing stuff like pulling down their pants.

Desiree hears a guy stuck in traffic wishing that his car could fly, so she grants the wish. The flying car gets out of control and Danny goes inside it to try and stop it to find Tucker. They fight and the car crashes into a farm.

Later, at Casper High, Danny catches Tucker altering his grades and tells him to stop. They fight each other for quite a while. Danny, eventually, leads the fight to his house, where his parents have a new invention set up in the lab. The invention separates ghosts from humans. Danny hits Tucker, causing him to fly through the invention. Ghost Tucker and human Tucker split into two, and Danny catches the ghost Tucker with the Fenton Thermos. Tucker apologizes, Danny accepts the apology, and Tuck learns his moral.
