Tree Mammoth Thomas and Palmetrodons Tim and Palmy

The tree mammoths are small mammoth-like creatures who live in the treetops. And the palmetrodons, on the other hand, are small Dimetrodon-like creatures with a sail that resembles a hand, and prominent teeth. Their threat display, seen in "Premonition", involves them snarling, showing their teeth and shaking their sails. They’re both seen together in some episodes of Angry Birds Stella.
