He got out complelety but knocked out again and got up a goes after him totally got Pat cornered by his burnt leg. He slipped off a rock by Shorty giving Littlefoot and the others an idea to roll more rocks at him and save Pat but didn't work. Bron came to the rescue since he heard a cry for help and made a smooth move to slide down and whip his tail by the leg to make him trip. This carnivore bite Bron's leg and got caught up by Pat's tail and Bron kicked his face and rolled downhill. He's not finished yet and calls in two other carnivores to join the brawl. He was completely knocked off by the grey one when Cera and Shorty made him trip.
