Only like the coolest pet ever. Homer Simpson's newfound friend that is compelled to walk across the ceiling while Homer sing's the theme song, only to leave dirty tracks to Marge's dismay. Isn't he the best!?

Introduced in the new Simpson's Movie Trailers.

The most anticipated and disappointingly shallow character in a movie since Darth Maul. Greatly admired nonetheless. Special abilities: does whatever a Spider-Pig does. Can he swing, from a web? No he can't, he's a pig.
Look out! He is the Spider-Pig.
