Nothing goes together more than Van Beuren and skeletons. The boneless beings surfaced in a bunch of the studio’s cartoons (not coincidentally after Disney released “Skeleton Dance” in 1929), such as “The Haunted Ship” (1930). It’s a fun cartoon with lots of sea creatures swimming around and past the camera, and a drunken turtle quartet.
Ah, but there are skeletons, too. The perpetually-shaking Waffles the cat pulls a chord that, for no particular reason, drops down from above. Skeletons clamber down the steps and do a little dance.
The petrified Waffles shoves Don dog at the skeletons and they bust apart. Don gets his revenge by tossing a skull at the fleeing Waffles.
Waffles looks up (we get a couple of hat-takes), sees the skull floating above him and then does one of those Van Beuren things where he leaves his clothes, circles around them and then goes back inside them.
