Inkblot Cartoon Style is the cartoon style most prevalent from the mid-1920s to the mid-1930s. Most historians refer to this as Rubber Hose Animation because characters' arms, legs and pretty much everything else are usually animated as if they were made of rubber tubing and without elbows or knees. In many cartoons in the very late Twenties and early and mid-Thirties, not only does everyone dance to the background music, everything dances to it as well. The style is widely considered Nightmare Fuel because of the genre's tendency toward surrealist humor.
