In "Surviving Sid", the protagonist is no longer just the unlucky squirrel. This time, Sid the sloth becomes a teacher for the little animals, teaching them survival skills for the Ice Age. Just like the squirrel, Sid continues to be extremely unlucky, leading to many awkward situations, and even demonstrates the concept of "chain reactions" to the kids through his actions... Scrat, making a cameo appearance, doesn't have his bad luck transferred or have his fate rewritten. Although he gets his nut back, it turns out he doesn't have the fortune to eat it. Poor guy.
