Bolivian Tree Lizard

The Bolivian Tree Lizard is a parasitic oviraptor that lays its eggs in other birds nests. After the eggs hatch, the young Lizards eat the mother bird too. The Bolivian Tree Lizard appeared only in "Bart the Mother" where Bart hatched a pair (whom he originally thought were the babies of a mother bird he accidentally shot) which he named Chirpy Boy and Bart Junior. When he brought them to the attention of the community a group of people (including his principal, Principal Skinner) decided that the lizards needed to be killed to protect the native wildlife. However, with the help of his mother Bart manages to flee with the lizards onto the roof; where both of them escape by gliding to the ground and running away.
