The unicycle section! Also, some skaters. (There's a separate bicycle joker section). The first unicyclist is particularly tricky.
This jester's unicycle is tiny but the tweetie bird on this finger is bigger than his head. And the bells on his hat are larger than the bird's head.
And a clown on a sort of unicycle. Actually, it looks like a ball. But I thought he belonged here with the others.
