My first one was the cave of many voices. My first thoughts were, how did chomper get into the great valley, who is that pink female dinosaur. It seems everyone, including the adults, knows Chomper is in the great valley and don't care, how did this come about. Isn't the pink dinosuar the same type as the egg eaters from movie 2, and no one seems to care.
Pretty stupid thoughts but those were my first one when I saw that episode.
