The Real Ghostbusters - Granny Gross, Ecto-2

Ghostbusters toys were the best. I remember they had that scanner Egon always used.

And the Ghostbusters don't realize something's not right with the old lady that has such an enormously large head?

Yep, I remember these commercials well, but I never personally had one of them. And Herald7, as a bit of nerd trivia, Egon's scanner was the "PKE Meter" (Psycho-Kinetic Energy)

The Peter doll with the "pop-out eyes" and "fly-up toupe" was the best! XD

i had most of the ghostbuster action figures..
i even had an echo 1
