This Real Ghostbusters t-shirt features an image of the Stay Puft Marshmallow Man, also known as Mr. Stay Puft. The image on this t-shirt is inspired by the destruction caused by Mr. Stay Puft in the Real Ghostbusters episode titled "Say Uncle". In the episode, Egon's uncle Cyrus released Mr. Stay Puft from the Ghostbusters' containment unit. Mr. Stay Puft went on a rampage before being captured again. Luckily for the Ghostbusters, Mr. Stay Puft proved to be much more gentle when he was released to battle Murray the Mantis. After that, Mr. Stay Puft was a friendly giant to the Ghostbusters and a popular character on the animated series. Let everyone know that you are a fan of "The Big Guy" with this Attack of the Marshmallow Real Ghostbusters t-shirt!
