Hyp, Mutt and Nod are a trio of adolescent dinosaurs, who first appeared in "", in which they often quarrel with Littlefoot, Cera, and the others. It is also implied near the end of the film that Hyp the gray dinosaur, behaves in this manner because of the aggressive treatment he receives from his father. His lackey, Mutt the green dinosaur, is shown to be much softer-hearted, as well as dim-witted, whereas Hyp's other lackey, Nod the green dinosaur, frequently emphasizes Hyp's statements, as well as allowing him to ride on his back. They become friends with the others after all eight cooperate against a pack of "Fast Biters".
