Not much is known about the Toy Ghost except it doesn't like to be disturbed. It resided in an abandoned toy factory in Brooklyn, New York after chasing off a Class 7 called Turlock. The entity was sleeping until its rest was disturbed by a Class 5 named Slug. The ghost became highly agitated and manifested as a one-eyed cloud of smoke.
Using parts from broken toys, it assembled a giant corporeal body to inhabit and took on the appearance of a giant mutant toy with the body of a stuffed bear, metal legs, and a large children's toy box as a head with a toy cymbal playing monkey on top. This creation then rode a gigantic tricycle. The Ghostbusters watched as the Toy Ghost burst from the factory in pursuit of Slug, Snarg, and Zunk. When they blasted the monkey on its head, a jack-in-the-box head sprang out. Unable to defeat the ghost through standard means, the Ghostbusters initiated a full power overload of Ecto-2 to disperse it on the Brooklyn Bridge. Slimer then slimed the bridge to trip up the ghost. It slipped on the ectoplasm and fell into the river with Ecto-2. It abandoned its host body and revealed its true form, a giant worm-like and multi-fanged monstrosity. Ecto-2 went critical just in time and dispersed the Toy Ghost.
He appears as a boss in The Real Ghostbusters Data East. In the arcade game, the creature appears to be visually resembling him, except it is orange instead of grey. It battles by thrusting its head at its prey.
This creature appears to be a very grumpy mood, likely because Slug woke it up. Although it's capable of speech. It only has two speaking lines. It spends the rest of its time growling and roaring.
The Toy Ghost is a Class 10,  one of the rarest types of entities next to a Class 11. At the time, Egon states it is bigger than anything they ever encountered,  implying it was one of the strongest ghosts in the series next to the Ghostmaster, a Class 11 and Cathulhu, who is "completely off the scale."
- Kevin Altieri noted the smoke form of the Toy Ghost was inspired by "The Crawling Eye," a black and white 50s Science Fiction movie. 
- Upon first seeing it, Ray thought the Toy Ghost was at least a Class 8 Free Roaming Vapor.
