Continuity mistake: In the Fairly Oddparents episode "Power Pals", when one of the Power Pals chucks a crystal into a drain to create "The Table of Frienditude", the crystal bounces under a table and into a drain directly under said table.

Continuity mistake: In the TV movie, "Channel Chasers," Vicky makes herself 18, changing the shape of her body.

But later she goes to face Timmy and she's 18 again.
Continuity mistake: This mistake is found in the episode where Timmy wishes himself into the Crimson Chin's comic book after causing the Crimson Chin to become depressed.
