I actually haven´t, but i was referencing the 2003 strategy game Impossible creatures, Which is a RTS based on early 20th century mad scientist vibes where you combine different creatures to battle for you. Could have tigers with scorpion claws, Giant whales with eagle wings and tons of other combinations to explore and experiment with.

My personal favorite is the Muskaleon, A giant Musk Ox with the head and tail of a chameleon, providing ranged attacks while being strong in numbers and able to stealth.
