Jodie at the left side of the window in the film.

Jodie (or Jody) is one of the supernaturals in the Amityville House. Jodie is a demonic, black-colored pig with glowing red eyes. She can be only seen in Missy's Room at the windows. In the 2005 remake, Jodie was not a demonic pig but the daughter of Ronald DeFeo Sr. and Louise DeFeo. It should be noted that the DeFeo's never had a daughter named Jodie.
