Random thought, but I was just thinking how neat a random event.. likely pay.. where you get to go to a zoo and there are a set number of rats, kittens, lizards, shade-skinks, squirrels, hedgehogs, gweedetta wigs, etc etc.. essentially all the random pet things. And people can run around and "find" the pet they want. Then a two hour window where a merchant or two offer to alter/customize said pet.
