Animal Circus (fan expansion for Animal Upon Animal) (2012)

Premise:

Each player is a circus manager with the primary act the animal acrobats that make up the pyramid in Animal upon Animal.  You will purchase animals to make the pyramid.  Some animals can easily woo the crowd and will give their owner-managers a bonus when they are successfully placed. Some animals are easy to come by and can even be obtained for free.  Some animals just aren't desirable and thus are easy to obtain, but likewise the crowd really doesn't want to see them either and you'll lose money for placing them.  Finally, of the animals fall they sustain injuries that cost money to treat them, even the birds can be injured by other animals in the pyramid.
