Mostly birds, some insects, a butterfly or two, and some dinosaurs. Yes, some of the birds, such as the penguins, are flightless. I don't have a swimming or sliding section for the penguins so they go with the flyers.
One of my long time favorites is the Bee Joker which I think was initially produced by Lewis Cohen and the New York Consolidated Card Company as part of the Bee 92 deck. It's a brand still published by the US Card Playing Company. You can read the US Playing Card History of the NY Consolidated Card Company The Bee Joker has a large bumble bee being ridden by a standing baby, dressed as a jester and holding a jester's wand or bauble.

The following joker was the featured Joker of the Month in November 2010 on the DXPO Playing Card website. This card and joker collection was started in 1996 and has been online since 2004. It's run by Miriam van Houten (more oriented towards jokers) and Joop Muller (more oriented towards decks of cards) from Zaandijk, a small town in the western part of the Netherlands. I find their website remarkable in the depth of research and insight associated with each joker. And I quote:
This almost surreal joker comes from the Fable III deck, which was included in the "Limited Edition" of the Fable III game for the Xbox 360.
