This Real Ghostbusters t-shirt features an image of the goblin-like creature known as the Boogieman. The Boogieman first appeared in the season one episode titled "The Boogieman Cometh". In the episode, two young children asked the Ghostbusters to capture the Boogieman. The Ghostbusters converted a room into a child's bedroom to lure in the Boogieman. Once the Boogieman arrived, the Ghostbusters set off a Ghost Bomb to imprison the Boogieman.
