The Skeleton Dance
The Skeleton Dance is animated short by Disney released in 1929, making this both the oldest and shortest thing I reviewed.
Its charming, whimsical, and playfully spooky. I love it. I think its great for younger children as an entry into spooky Halloween animation as its not that scary but its fun and not too long for their short attention span.
Its very family-friendly despite being very slightly spooky.
Overall, its a great simple short and its kind of awesome! S tier, 10 out of 10.
