The world that Heart City exists is both beautiful and hostile. One of the creatures that has made its way into city life is called a Rubber Bunny. According to the MINISTRY OF HEART:
Rubber Bunnies are everywhere, and are generally considered a nuisance in Heart City. They are small, no larger then a domesticated cat, and have very sharp teeth. They travel in packs of 20 or more, and can often be seen bouncing in and out of alleyways in the early part of the morning. They detest the smell of anything green or natural, and tend to favor living in garbage bins, piles of cardboard, or whatever else has been cast aside. Rubber Bunny colonies can be found all over Heart City, particularly near the Crystal Artery because of the constant heat that the cavern emanates. They hate water, flowers, and small children.
We’ve created this mock-up of a Rubber Bunny to help you spot them.

They are not vegetarian! Beware of them and watch out for the safety of your pets! There are many missing fingers and toes in Heart City as well as peg-legged pets. You may be able to kick one or two away, but packs of twenty have been known to take down grown men and livestock.
Be careful out there!
