A small dog escapes from his leash one night and chases a cat down with a well. Overcome with regret, he begins to fantasize spooky cat images in this decent Van Beuren Halloween cartoon.
Halloween and Christmas are probably the two biggest holidays for themed cartoons. Halloween is the one night a year where it's acceptable to scare little kids, and for decades, cartoon makers took advantage of the privilege.
Van Beuren was probably the weakest of the cartoon factories in the 1930s. You can see it here in the unadorned character design here. Still, they had access to the music scene in New York and took advantage of it to make some watchable music cartoons, like this one.
