Which monster do you find most irritating and why?

Well Ill Gills do many things. They can immobilize you for a little longer than Grass Assassains, but once they do such they're free to beat the @#$( out of you. They have a large sycthe that can shock, freeze, and 1-hit KO at quite a successful rate. They also charge at you which will knock you down even if it were to do 0 damage. Also, in Phantasimal World 4, there's a room with several Ill Gills at the same time, so if you get immobilized even once, you're basically dead.
