Me as a human in the start of the game...spawns in when almost everyone is dead and I and one other person is alive. My fav is when I spawn right next to a clown.
From what I've seen, to stun the clown for the full five seconds it needs to hit their nose, and when you hit the body or head it's a short stun, like 1 second.
When editing I realised, a nose hit shows up as "Bullseye" instead of "Domed" and that's the full stun, a headshot does the short stun, and a body shot slows them down a lot but they can still attack
