Theory of bees in Amdapor Keep:

Point 1.
Bees is a four-letter word. Gnats is a five-letter word.
Point 2.
Gnats are annoying. Bees are more than annoying, much like how the gnats were to people when they encountered this boss for the first time.
Point 3.
Look at your keyboard. G and N are relatively close, but then- A. It's so far from N. There are very few words that begin with GNA. It's just... inconvenient. The final letter, T, isn't so bad as N to A, however the whole thing is just so awkward to type. How long does it take you to type gnat vs. bee?
Point 4.
I like to use my BLM LB on the bees. Hue.
