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, which was built over an ancient indian burial ground. As a result, the fish is evil, 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.
