Continuity mistake: In the movie "Channel Chasers," when Timmy and Vicky go into Maho Mushi, Timmy gets a piece of his hat sliced off and Vicky gets the tip of her ponytail sliced off. But in the next shot, they're both back to normal.
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: When Timmy first finds the place in the license plate maker where you stick letters in, there were 7 slots, but later when we see him spelling "I wish I was ten", there are 12 slots, enough to fill in that sentence, without the spaces.
