I noticed that bees don't just drift randomly, they home in on nearby flowers. This made me wonder how they behave in other areas. So I started pushing them into the stony field.
Even though the stony field doesn't have flowers, they tend to drift north-west.
Then I pushed them into the orc cave.
For the first time, I saw an orc kill a bee.
Bees and rabbits are scared by humanoids, including orcs and NPCs, so they coagulate at the walls when pushed inside the hut.
