Buck and Blaze, the juvenile Maiasaura acting like rebellious teens. In fact, the narrator says that their favorite game is called "Walk away from the herd and let everyone know".
Little Das' mother declares with a deafening roar that it's time to finally close in on Buck and end their hunt, and they march off to do so... and a dead Quetzacoatulus drops from the sky right in front of them, to the absolute bewilderment of the pack.
A young Dragonfly meets Alpha for the first time, and has her all to himself, and is ready to attack... only to be distracted by a dragonfly buzzing by him. Even the narrator lampshades this when he says "Dragonfly's attention span is pathetic."
During dinner, Dragonfly and his sister start growling at each other only for their father to roar at them to quit. They bow quickly as if to say "Sorry, Dad".
