Gumball's Department Store is a retail chain in New York City.
On October 6, 1988, Slimer visited a Gumball's in search of a birthday present for Chilly Cooper. After scaring the third floor manager in cosmetics, Slimer played a game of cat and mouse with Bruiser, part of the store's security at the time. After handing Bruiser in Sporting Goods and Radio & TV, Slimer gave him the slip by shipping himself out of the store.
- On page 19 of Ghostbusters Volume 2 Issue #5, Gumball's has a non-canon reference on the directory in the elevator.
