The Grim Adventures of Billy & Mandy: Prejudice and Appearance
Billy, suffering from entomophobia, finds an odd egg in Grim's trunk. Billy imagines a duck would hatch from such a large egg, but a giant spider who Billy names "Jeff" emerges, freightening him. Jeff visits Billy that night as a fully-grown giant spider, referring to him as "Dad". Although Jeff is mild-mannered and friendly, Billy cares more about the fact that he's a giant spider and wants him "squished."
