Most annoying enemy in the game?

[Blaaaaaaaah]

but the one I found most annoying was the King Staff because the actually monster was so high up that you couldn't even see it.

LOL YEAH! I remember once, I was training in moonlight tomb for the first few times with Chinh and Phizzie, and we were dying heaps at the staffs passing by. There was a point where a lot of them chased us, chinh died but me and fuzzy had to leave him back there or else we'd die, and when we ran away to a certain point, we stopped saying "phew", only to find us facing a king staff! Then we were like AHHHHHHH and running back, LOL! It was like those cartoons thingies where characters tries to run away from something but bump into another anyway.
