While trying to be friends with Sharpteeth, the next morning Chomper decides to spend the night in their cave. Realizing that he was there, they growled and Chomper heard them. He said, "I'm sorry. I didn't know anyone lived here but maybe we could be friends?" they growled in response and he said,"Right! You speak Sharptooth! Um..." he roared in response but no captions were added to these Fast Biters. They don't understand Chomper and give chase to him.

Chomper ran for his life with the Sharpteeth close behind him. They reached a big fallen hollow tree trunk. Chomper made it safely underneath, but the gray Fast Biter couldn't get his teeth under the tree trunk (as it was too large, too closed, and too narrow for a huge Utahraptor to get through). Its two counterparts then came crashing into him.

Meanwhile, thinking that he had escaped the Sharpteeth, Chomper said to himself, "Whoa, that was close!". He then reached a steep cliff which led down a slope to a raging river below. Just then, the red Fast Biter and his two counterparts came charging right at him roaring loud, so he hid. He found a place to hide as they came over, snarling and growling. The Fast Biters see a rock that Chomper threw and follow it. They start down the slope but the gray Fast Biter accidentally slipped on the slope and he went tumbling into the river below with his two counterparts.

It is unknown if they survived. They may have drowned or swam to shore.


  • The green Fast Biter look similar to Thud, one of Red Claw's subordinates, except that this Fast Biter's green color is more dull.
  • It is unknown as to why the Fast Biters didn't understand Chomper when he spoke in Sharptooth language. They were possibly hungry and were following their predatory instincts.
  • Incidentally, these three Fast Biters have the same coloring as the sharpteeth from The Land Before Time X: The Great Longneck Migration.
