Continuity mistake: When Ron is showing Eric the lunchroom, Eric points to Kim and says" Who's that?" We see Kim getting her lunch in a blue tee shirt and brown pants. Ron and Eric sit down. Kim joins them, now she is wearing a red tee shirt and grey pants, however.
Continuity mistake: In the first 'Ice Age' Diego isn't afraid of water (in the beginning he chases the woman and the baby through the river before she jumps off the waterfall and never shows any fear) but in this one he suddenly is. It's not like that he is just afraid of swimming because in the second movie he shows fear anytime when he touches water.
Continuity mistake: In the end, all the pictures in the cousin's book are normal, but earlier Leroy tore Xs in each.

Continuity mistake: The group who set out for Flutter Valley are chased by Ahhg the giant spider after tickling him and slipping away unnoticed. As they make a dash towards a nearby cliff, Gingerbread (white Pony with purple, pink and blue hair) and Baby Lickety Split (light purple with pink hair) have somehow joined the group, but Baby Lickety Split should be with the Grundles and Spike and Gingerbread should be back at Paradise Estate.Blue Phoenix
Continuity mistake: When Donnie steals Chuckie's clothes and glasses, Chuckie puts on Donnie's shorts and complains about his eyesight. But later in the movie, when he doesn't have his glasses, it seems he can see just fine. Then, when he gets his glasses back, he says something like "I can see again."
Visible crew/equipment: Thin wires are visible, attached to the crystal bats as they fly off to watch Jen and Kira.
Plot hole: There's no visible evidence that Team Rocket has taken away Ash, Misty, and Brock's Poké Balls when the gang was in the cage, so why don't the Trainers call out their Pokémon (Brock's Onix would've helped out very much) and escape the cage?
Continuity mistake: In the scene where the Griffins are having breakfast and Stewie is drunk, Brian has one egg on his plate, and some bacon. After Stewie jumps from the shelf, Brian has two eggs and no bacon.
Revealing mistake: When Akane is sneaking out to the kitchen in order to cook something she briefly has a see-through hand, the animators haven't added any pigment and you can see the background cell perfectly.
