A majestic and mythical creature. It is generally a very cheerful and sociable animal that enjoys the company of other creatures, mainly rabbits.
Often hard to communicate with as it has a tendency to sleep at abnormal times, and has no exact sleeping pattern. It is neither nocturnal nor diurnal, and its sleeping patterns is hard to predict. It exists predominantly on a diet of curry and baffles medical science as it never appears to suffer from malnutrition. You will be very lucky if you come across a bumwin, as they are a rare and endangered species.
