Here Grug is about to be trampled by a pack of Liotes – a creature that is a combination of Lizards and Coyotes. Grug is chasing the Liotes, who are in turn chasing a huge flightless bird, who is carrying the egg that Grug wants. In the midst of the pack, Grug slips. After being trampled, one of the Liotes lingers for a little payback, then moves on. Moments later Eep streaks past, easily passing the Liotes and reaching the huge bird.
The Liotes developed a lot of personality in the early boards, which they retain in the finished film.
