The short takes place during the events of Sonic Unleashed. In it, Sonic and Chip enter a Haunted House that's haunted by three ghosts. Two of them, Su and Wu, fight over Lah's affections by taking photos of people they scare. Though Chip scares easily, Sonic doesn't. Unbeknownst to the ghosts, Sonic can transform into something even scarier than a ghost.
Sonic: Night of the Werehog was released online in November 2008. It was animated by Marza Animation Planet.

- Mime and Music-Only Cartoon: The short contains only five, one word lines of dialogue. Despite this, it has both an English and Japanese version that replace dub over the words.
- Morphic Resonance: In the ending, Chip has a pink heart mark on the left cheek, which means he's really Lah in Chip's from.
- Nerves of Steel: Sonic is not scared at all at the ghosts, and even teases them by making a face, disappointing both Su and Uh and Lah.
