As well as having pigs, chickens and butterflies, how about also having a pet of some sort? One that you could teach new tricks too and buy some stuff for it like collars, leashes, bowls and toys. There could be dogs, cats, fish, hamsters and even turtles. Turtles would be super rare and hard to find occasionally being found in the water(New Animals: Sea Creatures). Also you would be able to buy dog houses or an aquarium for your pets. What do you think?
