Could you clarify your question?
Here are some possibilities:
* Are you asking for a type of beer named after an animal? Many breweries use animal names for their beers, like "Bearded Owl Stout" or "Black Cat Porter."
* Are you asking for a beer that *tastes* like a particular animal? This is a bit trickier, as most beers don't aim to replicate animal flavors! Perhaps you're thinking of a specific flavor profile?
* Are you asking for an animal that is associated with stouts? Stouts are often associated with strength and darkness, so animals like bears or black cats might be fitting.
Please let me know what you have in mind, and I'll be happy to help!
