Ice Age 2: The Meltdown (2006)

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.

Plot hole: At the end of the movie, when the water drains away, there would be no way for a) the amount of water to drain away that did and b) for the mammoths that came through to be completely dry. (01:16:20)

Continuity mistake: In the scene where Scrat gets attacked/attacks the piranhas, the acorn gets swallowed by a piranha on the right, after all the fighting, Scrat jumps on a piranha on the lower left, which spits out the acorn. (00:35:20)

Trivia: The movie contains a spoof of Saving Private Ryan, where Manny is hit by a geyser and temporarily loses his hearing. Incidentally, the German voice for Manny, Arne Elsholtz, also synchronizes Tom Hanks, who also stars in that movie, which creates an inside joke by happenstance in the German version.

Trivia: In the trivia game on the DVD, one of the questions asks how many Possums were seen in the movie. The accepted answer is 2, but the correct answer would be 3: Crash and Eddie's mother is shown in one of Ellie's flashbacks.

Manny: Don't listen to him, folks. Fast Tony would sell his mother's ashes for a grape.
Fast Tony: Is that an offer?

Diego: Congratulations. You're now an idiot in two languages.

Manny: Sid, I'm gonna fall on you again, and this time I will kill you.

Question: What species are the water creatures that Manny fights against at the end of the movie?
