The Great Ping Pong Scam - S1-E11
Plot hole: When Cat, Beck, Robbie, Jade and Andre are telling Tori about why they faked the Ping Pong team, it shows a flash back of two years ago when Tori hadn't started at Hollywood Arts yet. But in the background of the hall when they are asking for Sikowitz to help them, Tori's locker is there - how can her locker be there when she hasn't even started at the school yet? (00:12:25 - 00:12:55)
Shrink It Up - S2-E1
Continuity mistake: When Rocky is saying things that she has been pushed into doing, she mentions the time they danced on the wings of a plane. However they didn't do that until a few episodes later.
Plot hole: In the episode where Gabe wants PJ and Teddy to pretend to be his parents when his teacher wants to see them after getting in trouble at school, it is established that Gabe's elderly teacher is short-sighted. When he asks "How many fingers am I holding up" his teacher gives an incorrect answer. However, later in the episode, his teacher spots Teddy on a date at the cinema (movie theatre) and assumes she's cheating/having an affair. How could she have seen Teddy from a row in-front, when Teddy is facing the audience and not the teacher, if she couldn't see how many fingers Gabe was holding up close to her face?
Continuity mistake: When Granny tells Sylvester to stop chasing Tweety Bird, he comes to a stop and Tweety Bird keeps going and is ahead of him. But in the next shot, Tweety is now behind Sylvester (between Sylvester and Granny), however, there's not enough time for him to fly back that far (or even circle around), and we would have seen him do it.
Speeding Is Dangerous - S1-E22
Other mistake: When Shine says, "I think I'm OK," his front tire is layered over the railway tracks.
Pumpkinhead - S2-E5
Continuity mistake: One of the pumpkins that the kids bring home is completely different to the ones they took from the pumpkin patch.
Suggested correction: It was Ponnie's locker. Remember in the episode "Crazy Ponnie", she was like "Your locker used to be my locker!"
No, because Ponnie's had to be decorated differently. Why would she put "make it shine"?
