Weird MMO Enemies

So, playing IRO (Ragnarok Online), and I'm walking through an area. The enemies in the area are decently mid-level, about level 55 give or take five levels, and are not aggressive. One of the enemies is basically a giant grasshopper with a violin; the other enemy in the area (yes, only two enemy types in the area) is a fried egg wielding a frying pan. So I'm just walking through the area, minding my own business, when 1 of the fried eggs starts casting a spell, suddenly, I'm blind. I got randomly blinded by a fried egg. The fried egg did nothing else, just the blind. Like why literally no enemies in that area are hostile, it was just a random blind for no reason whatsoever, and why is a fried egg with a frying pan an enemy. I have so many questions. If anyone knows why MMO enemies seem to be the most random things, please, let me know.
