The Weevil is a hobo who will eat ANYTHING. Blockhead introduces him to Conscience in Episode 10. He apparently was and is in an asylum. Blockhead will take The Weevil on his adventures. One example was when Blockhead wanted to show Halloween a thing or two in The Ghostmas Special. Another one was when Blockhead busted The Weevil out of the asylum to help him with Ghostmas, only to go back there in Episode 11.
