Crocoduck
One of the most prominant icons of modern day Christianity, the Crocoduck is capable of dispeling all arguements in favour of Atheism and Darwinism simply by not existing. Its sworn enemy is the platypus, which, in harsh contrast, is capable of proving god does not exist by existing.
Kirk Cameron: All throughout the fossil record and life, we don't find one of these; a Crocoduck. There's just nothing like it!
