Skeletons

The "Skeletons" are characters that first appeared in one of the classic Silly Symphonies, specifically the first entry in that series, The Skeleton Dance, which was released in 1929. The skeletons are obviously undead walking "creepers" and have been long associated with the macabre side of Disney.

The Skeletons have made numerous other appearances in other cartoons such as The Haunted House and The Mad Doctor.
