Personally I find the fish monsters in Padova Mts EXTREMELY annoying. They hurt, first of all. Their attack is really long range. And it's timed PERFECTLY to piss me off when I'm watering. I finally get to the last level of charge and let go of the B button to water, and then during the watering animation they release their annoying little beams. Of course they BOTH do it, and they BOTH hit me twice so it's like 60-100 damage - not to mention they cut off my watering animation so I have to start charging all over again. This sucks, especially in the rush of the morning when I need to get to all, or as many crops as I can, in 3 hours. My wolf doesn't even attack them because they attack from so far away. UGH they just anger me so much
Another one is those Tundra things in Padova Mts; less annoying, but still. They go along creating these ice patches while chasing after you, then the second you turn around, you run into one and the thing disappears -___- For these you can charge your weapon, and unleash a "long-range" attack and that will usually get rid of them, but they still annoy me.
Anyone else have that monster they just want to murder?
