Plot hole: In the Ice Tunnel scene, Manny, Sid, and Diego come to a stop on the vertical block of ice. It breaks, and they slide through a 'field' of icicles sticking out of the ground. Their 'sled' is shaved down to nothing, indicating that the icicles are sharp. After going through the same tunnel as the baby, how did the baby make it through that field? (00:46:53)
Question: The end of the movie shows Scrat and his acorn frozen in and eventually thawed from a block of ice 20,000 years later. How did he come back for the sequels?
Question: When the baby pulls Manny's nose hairs out, there were white things at the ends. Not to sound gross but I've done it in my nostrils and my armpits, and I wanted to ask what those white ends are?
