Mattel’s Gre-Gory was an 8-inch-tall rubber toy bat with a 12-inch wingspan. Gre-Gory’s chest was devoid of flesh or bone, leaving his internal biology visible. By pressing a button on his back, you could make his “red liquid” (the adverts were careful not to call it blood) flow.
The comic book ad ordered kids to “put your finger in his mouth – and see what happens when you squeeze him!”
What did happen was that Gre-Gory’s rubber teeth bit down upon your innocent flesh (but caused no physical wound).
To inflict actual harm, you needed to throw Gre-Gory at someone (kid brother, little sister). Despite the claim that the bat was made from “soft, flexible material”, the thing was extremely heavy and could pack a punch when hurled at speed.
Mattel later re-used Gre-Gorys blood pumping feature in the Masters of the Universe figure, Mosquitor.
