Adventure Hook: Circus

The circus has come to town along with all of its animals, clowns, jugglers, acrobats and other performers. Unfortunately for the town several of the more dangerous animals have escaped from captivity and are now roaming the town. The ringmaster of the circus hires the PCs to gather the animals and return them to their cages. Of course, the circus wants them back alive. Meanwhile, the town has put a bounty out on the animals that are wreaking havoc in the town and wants them dead. The PCs are in a race against others to capture the critters before they are slain.
