Poultra is a villain in The Adventures of Jimmy Neutron: Boy Genius, first seen in the theatrical movie. She is a giant reptilian monster resembling a chicken, whom the Yolkians worship as their goddess. In the movie, they try to please her by capturing all the parents in Retroville for her to eat, but thanks to Jimmy and his classmates' efforts, this is foiled.
Later, in "The Eggpire Strikes Back", it is revealed that Poultra left Yolkus to go rule over another planet, so King Goobot steals Jimmy's DNA Regenerator to create a clone of her. She is eventually lured by Jimmy to drink a large soda tank and eat an essential Pop Rocks dummy, which causes her to explode due to being unable to belch.
