Let the dice fall…
Every gamer who has ever played D&D has likely had some encounter with the weird hybrid monsters of the game, typically blamed as the result of wizard experiments. What the heck kind of experiment results in a wolf-duck? Was it successful? It’s hard to imagine someone being happy they created a monstrosity whose first instinct is to eat itself.
I suppose “wizard experiments” is a more likely justification than the other option: a mama owl and papa bear who love each other very much, and likely get really drunk.
A horse zebra?
