SONIC: NIGHT OF THE WEREHOG - Sonic & Chip Kyoufu no Kan

An original online anime released in November 2008 on SEGA's website, this short was created to promote Sonic World Adventure, later known as Sonic Unleashed in North America and Europe. Sonic and Chip visit a deserted haunted house during a stormy night and encounter two playful ghosts who scare visitors to take their pictures and impress a ghost girl living with them. The ghosts manage to frighten Chip severely but fail to affect Sonic. Enraged, the two ghosts combine efforts to outwit Sonic. With assistance from the full moon, Sonic must find a way to stop their antics.
