Arthur Rizzic appeared in the Dinosaurs episode "The Mighty Megalosaurus." A mammal with a protruding snout, Rizzic escaped from the dinner table at the Sinclair Home, only to find Earl had destroyed his tree home. After Earl spared Rizzic following a heart-to-heart chat, the prey creature became B.P. Richfield's personal assistant. Rizzic manages to convince B. P. to give Earl a raise, probably as thanks for Earl sparing his life.
