Like Meghan, Buddy isn't seen a lot through out the movie. He loves being by Ethan's side and being cool. When Peaches, incensed at the groups' casual attitude toward danger, remarks that the mammoth species will become extinct if they are the norm, Katie shoots back that her species will be extinct too, to which Ethan's Buddy adds "Burn!" When Ethan points out that they are the same species, he says "What?! Double burn!"
