The Puppet Dimension is one of the numerous dimensions within The Grim Adventures of Billy & Mandy. Not much else is known about this world, only that it is inhabited entirely by seemingly living puppets. Its only appearance in the series was in the ending credits of the episode Guess What's Coming to Dinner?. Eris is capable of sending others to this dimension if she wishes. Hoss Delgado was sent to this dimension by the Goddess of Chaos herself after he attempted to bring her in.
It appears that anyone from other universes beyond this one becomes a puppet themselves once they enter this dimension, with Hoss being the only example.
- The scene where Hoss woke up in the Puppet Dimension was actually filmed in live-action with actual puppets being used.
