Journey with me to China to observe a monster from the 1964 Cantonese film: Buddha’s Palm.
I believe this is the the first recorded instance of a Yeticorn!
It predates the Mugato by 4 years. Note: I don't count the 1936 Flash Gordon's Orangapoid, which isn't yeti-ish enough.
Did you know? The Buddha's Palm yeticorn can spit lasers that instantly skeletonize its target. And for that, I must tip my hat!
