In the Goosebumps episode, Patrick Thomas (as Greg) was fitted with a fat suit and given fat face prosthetics when Greg becomes obese. In earlier weight gain scenes, Patrick is only wearing a fat suit and has cotton balls in his cheeks. However, in Greg's fattest form, fat makeup had to be applied to the actor. Stefaniuk FX Studios were responsible for turning the skinny actor into a fat kid.
- According to IMDb, Goosebumps was Patrick Thomas's first acting role.
- Patrick Thomas guest starred on two episodes of Are You Afraid of the Dark? as well as playing Malcolm on Vampire High.
