And my favorite, when they throw barrels at you but hit their friend instead! Always a classic. And how they pick up weapons you drop for them, even terrible ones like spoons, tree branches, etc.
You can kinda "build a better moblin" by dropping Lynel weapons around them, which is a little...
I love how feisty and coordinated Bokoblins are. And they have little wake-up parties, and chase around wildlife (boars) to hunt and eat them. When they see you they blow their lil' horns and chase you down as a team, just a really well-realized enemy with a lot of personality!
