I am not a fan of the Scrappy series of cartoons made for Columbia from 1931 through 1941. They seem made for small children without a clear understanding of what children find interesting.This one, however, starts off with an extravagantly terrifying opening as Scrappy finds himself in a laboratory, where a scientist keeps injecting him with serums, changing him into various weird life forms. The dark ambiance and better-than usual in-betweening lend an eerie air of nightmarish reality to the entire proceedings.Unfortunately, the second half of the cartoon moves into a science-fictional but relatively banal story in which Scrappy and a bad guy chase each other around for a while. So this is not a great cartoon, but for those first three minutes it is first rate.
