- For the episode with the same name, see "Spookyfish".
Stan's Aunt Flo is visiting, and arrives with a gift for Stan, a small goldfish. Unbeknownst to Stan, Flo bought the fish at the Indian Burial Ground Pet Store. As the name implies, it was built over an ancient Indian burial ground. This had caused a portal to open to another dimension where the evil pets come from. Therefore, the fish is equally devious and kills several people while in Stan's care.
The first person the fish kills is an unnamed man with a green shirt in jeans. Stan wakes up the next morning to the fish having killed another person, a blond man with a blue shirt. The fish then kills Aunt Flo and Kenny McCormick while the boys are visiting.
Spookyfish is a small goldfish that lives in a fishbowl with plastic kelp.
