The Abominable Snowman character is inspired by Lon Chaney Jr.'s performance in Of Mice and Men (1939). This may also explain why he calls all other characters George.
The background art here, especially of the desert resort, has become more modern and abstract, as the 60's moved forward. There was still plenty of color, including the oddly hued yellow skies seen in some WB shorts then.
