Gumby was an animated clay figure who, along with his horse Pokey, had a TV series on television in the 1950s.
The Gumby bubble blower is an unusual one. You put bubble solution in the red square and then you bend Gumby's arm down into the solution. The quite unusual part is that there is a red "hose" that you push into Gumby's mouth from behind. You blow through the hose to make Gumby blow bubbles.
