This creature was developed for a scene in the 5th chapter of our book where we have a chance to see what's left of the animals in our world outside of the laboratories. Some time in the past, most of the animals of earth became extinct due to the land destruction and incredible pollution, so humanities answer was to bioengineer a stronger breed of animal to exist in our bleak future. What happened, unfortunately, was the creation of abominations like these. Disgusting half-breeds of birds and mammals, fish and insects, rodents and amphibians. You get the picture. So now, the government is doing it's best to catch and dispose of these hideous freaks of nature, but they still plague many areas of the city. So keep your eyes pealed, and you'll see what god never meant you to.
