Over the years, the theme park's marketing people have used an image of a Yeti (the monstrous spirit of the mountain (aka the "Alpengeist")) to promote it. Great minds apparently think alike - am I right?
I had to do quite a bit of digging around to find the below images. You can thank me later.
Hong Kong Phooey (1974) had an episode The Abominable Snowman (watch here) where a human criminal nicknamed "The Abominable Snowman" steals ski lift equipment to make his own ski lodge. There is no Yeti.
In Rocky and Bullwinkle's Jet Fuel Formula (1959-1960) - the longest running story arc for Rocky & Bullwinkle, the two aliens Gidney and Cloyd (pictured) allegedly disguised themselves as an Abominable Snowman.
Snooper and Blabber (1959-1962) episode Scoop Snoop has this plot: "Snooper and Blabber travel to the Himilayas to photograph an abominable snowman. Blabber gets successful photo shots."
