Usually, there's some building up of tempers on both sides when Donald faces off with his nephews, and the humour comes from how much everything escalates. In this one, there's no build up. It's go from word one with this duck. No mercy on Halloween.
Whatever, Donald. Next year, just give the children candy.
Donald Duck and the Gorilla was released in 1944, and it's exactly what you'd expect from the title, but maybe a little scarier. Often featured in Halloween-themed Disney compilations, you could probably watch it any time of year.
I always really enjoy that lollipop gag. Can't help it.
