Continuity mistake: Fleeing from the giant crab, Sid runs to the leading edge of the huge ice float. Two shots later, the camera displays the leading edge of the ice float as it begins to go downhill, but Sid isn't there anymore. (00:18:00)

Continuity mistake: In the shot when Granny talks about her dead pet and the young male sloth complains about it, the uncle sloth can not be seen between them, but instead appears between them in the following shot. (00:05:25)

Other mistake: The way Sid interacts with the whale's blowhole is illogical in relation with the manner the water is being discharged. When viewing Sid up close, it is seen that the water stream is divided and outspread due to Sid's manner of blocking parts of the blowhole with his body. Despite that, when viewed further away the water stream is intact and traveling straight ahead. Once the water stream is seen doing just that, the following shot shows a boar getting hit by it as if it somehow hadn't already occurred, not only that, but the stream of water that was displayed in that shot was delimited, despite the water discharge never being paused and Sid never changing positions. When Sid starts rotating, delimited streams of water are seen traveling in various directions one at a time, when there should have been multiples at a time according to what is viewed when close to Sid.

Continuity mistake: In the shots of Scrat getting flung away after tripping and then bouncing between the inner and outer core, the distances between the inner end of the outer core and the inner core are completely different. (00:02:10)

Deliberate mistake: Some of those branches would definitely not have been able to support Peaches' weight. (00:04:00)
