I swear, I swear, folks, I do not make these things up.
While researching old, creepy doll gifs and vintage YouTube commercial vids to scare the living hoo-ha out of my sweet little grandchild, I came across a lot of things. The doll ads were the best: Betsy Wetsy, Tickles, and Bonny Bride who glides along on a wheeled contraption under her wedding gown and hurls her bouquet from a springloaded arm.
Some of the old toys I hadn't heard of however, including one construction set called Blippo the Builder. Looked like a cross between Dinky toys and the old Meccano set my brothers owned.
But then I got a good look at Blippo. Ye gods! Where had I seen that face before??
Whoever designed Super Mario Brothers, whether consciously or unconsciously, ripped off the likeness of Blippo. It simply couldn't be anyone else. Same hat, same overalls, same moustache, same EVERYTHING.
