Tip:
Every attack can be parried, even the meteors. And also attack his hands as fast as you can when they are not moving/attacking. I also recommend using skater blob as it’s good for the boss and NOT slapper
I thought about making a giant BOSS, something like this one, but I got lazy.
In case I ever do it, let me tell you that I wasn't inspired by this, unless the skills are specifically similar.
