Before you can “stage your own supernatural battles” The Real Ghostbusters need to be apart of it too. In 1986 Kenner knew what we were asking Santa for. Each The Real Ghostbuster came with a proton pack (built in colorful proton streams included) and Class II looking ghosts to bust. Other accessories wouldn’t be included until later figure lines.
Whomever at Kenner who designed this figure card misspelled Winston’s last name. Honest mistake I presume. Winston’s proton stream is yellow and his ghost figure is Chomper Ghost.™ Yeah, I know my Chomper Ghost’s™ part of the plastic has a dent in it.
