Birger

Birger is a bird-like tiger-like animal that appears only in Dawn of the Croods TV series.

One appeared in Flowers for Munk.

Their butts are called "buns" which is a play on hamburgers which are often abbreviated as just 'burgers'.

Trivia

 * The Birger also resembles the griffon due to its bird-like head and wings, and cat-like body as well.
