By itself this Enemy is quite weak, but when it starts appearing in huge groups, it's not as easy. Its Freeze can be very annoying, though it won't hit much besides the meatshields.
Strategy[]
The best way to deal with huge groups of these enemies is by using Area attackers that have higher than 200 range such as Figure-Skating Cats, Pizza Cat, and Ururun.
