|Voiced by||Dan Castellaneta|
The Screamapillar is an endangered species that takes up residence in a Koi Pond in the Simpson family's backyard. It is large and red and is similar to a caterpillar.
In, The Frying Game, the Screamapillar is easily identified by its constant screaming—it even screams in its sleep. The Screamapillar is the favorite food of everything, is sexually attracted to fire, and needs constant reassurance or it will die. After learning all of this, Homer remarked, "You sure God doesn't want it to die?" One way to reassure the Screamapillar is to burp it like a baby. Marge discovered that when the Screamapillar is burped, it spews copious amounts of vomit.
The Simpsons were forced to take care of the Screamapillar by the Environmental Protection Agency. The EPA Scientist told them that because the Screamapillar had chosen to live in their yard, they were responsible for its well-being. He gave them a booklet which explained how to care for the Screamapillar.
Homer nearly killed the Screamapillar (accidentally), and he was sentenced to 200 hours of community service. When Homer was later sentenced to death for another crime, the Screamapillar smiled and laughed when Homer was in the electric chair.
"Giant Screamapillar" in the ComicsEdit
A giant version of the Screamapillar appeared in The Simpsons Super Spectacular Volume 4 comic book in a comic strip called "Scream a Little Scream." The giant Screamapillar tried to eat Rod and Todd, but Bart turned into Bartman and saved them. At the end of the story, it was revealed that this was actually a dream, but then the original Screamapillar was seen outside in the garden. The giant Screamapillar's abilities include biting, hitting with its tail, and screaming a supersonic scream.
The Simpsons Super Spectacular Volume 4 mentioned a strange language called "Screamese" that the giant Screamapillar can speak, but the only word in the language is "EEEEKKKK!"
