Dude, That's My Ghost!

Trying to help Spencer get an authentic-sounding scream to use in one of his movies, Billy scares Mallory so badly that she decides to move far away.

Ponzi finds a `no weirdos' rule in the school handbook so invites himself to the Wright home to get the evidence he needs to kick Spencer out of school.

Spencer fears he's going to bomb at the school talent show, but when Billy gets mixed into a batch of Jane's brownies, Spencer's got bigger problems.

Billy turns Spencer into a ghost; Billy feels neglected when Spencer pays more attention to a new video game than to him.

Spencer's plan to use Billy's ectoplasm to become famous goes badly wrong. Spencer's blackmailed into filming Ponzi's life story, and relies on Billy to sabotage it.

When Spencer shoots a movie in his pool, Billy's ectoplasm turns the film's harmless goldfish star into a fearsome aquatic monster. Spencer's sister develops a crush on Kleet, and the bully sees an opportunity to spend time tormenting him.
