Fan Casting Bilbo in Prehistoric Age

A clumsy Alphadon, "kinda" baggy, but equally kind and with good intentions. He was abandoned by his own family and, since then, he tries to live life using his "smartness" to get out of trouble. He ends up meeting Carl after being saved by him from two dinosaurs that were trying to crush him, where he decides to stay by his side, even if at first Carl tries to get rid of him.
