The Groundhog's Shadow is the patron of Groundhog's Day. It was originally a shade in Halloween before getting its own holiday. Bun-bun summoned it with the Book of E-Ville in hopes of removing his Easter patronage, but Torg accidentally bound it to Bun-bun with an ambient halogen light. It mostly tortured Bun-bun with poorly sung karaoke and Oprah Winfrey before 2002's misguided attempt to save Santa Claus revealed to Bun-bun the value of holidays. The shadow then became Bun-bun's main source of information on holidays. It was briefly given solidity when Bun-bun acquired a majority of the holidays. The shadow foolishly slew 2003 seconds before the year ended, forcing Bun-bun to use the Deus Ex Ovum to save his own life. The Deus Ex Ovum returned the shadow back to its original groundhog.
