There is this guy who is making what he calls "animal scrapyards" on a dare by a friend - he makes freaky creatures from three named animals. Currently I've only found two, but they're great:

Tree Frog/Orangutan/Narwhal

Shark/Spider/Jellyfish

I really feel this level of "WTF" fits the shop, and what we are trying to aim at. Slightly cobbled together, slightly matching, all nightmarish.
