Rocko is a legenedary slime, said to blast anything too outer space. Once you enter his floating arena, he'll suddenly jump, and a crowd of Slimes (which has all of them except the ones you didn't discover) cheer for Rocko. The a HP bar will come out, the HP bar says "Rocket Blast" hinting Rocko's real name. It has 1000 HP.

Rocket Roll! Rocko starts spinning, then starts rolling. After it's charged, it'll lunge toward you. Try and make it hit Pineapple, who just spins. He'll be stunned, meaning you could try and vac up his hidden tail. Then, try to launch him out of the arena.
Charge! Rocko charges at you, then starts rolling.
Omega Jump! Rocko does a mega jump, and Feral Boom-Rock largos come in. You have to beat them all, else they will be send flying, and explode.
Fire Works! Rocko summons a Magma Suit, running around, setting the floor on fire.
A Bundle of Slimes! Rocko summons random feral slimes to attack you.

Phase 2 Attacks

Attack What it Does
