"Does this look like the face of mercy?"

Despair Slime is a Hidden Boss that you don't have to fight in order to fight Lord Goldarr or Apocalypse Slime. However, that doesn't mean he is an easy fight.

How to Fight

Throw a Plort at Despair Slime when you see it. Once you do, a cutscene will play; Despair Slime looks at the plort you threw at it, and assumes that you were trying to make a largo with it. Upon false realizing, Despair Slime will emit a Dark Aura, and the screen will go dark.


Normal Form

Despair Slime is a White Slime with Red Eyes.

Despair Slime has many attacks. Here are all of them

Attack Name Description
Telekenetic Aura Despair Slime summons a glowing purple ball of light that he throws at you. Don't let this ball of light get near you though, because if it does, it will lift the player up and smash you onto the ground.
Twister of Royalty Taken straight from the Phosphor Queen, Despair Slime spins around, making a tornado. If it touches you, it flings you away from it, dealing two thirds of your health.
Cactus Shooter Taken straight from Grass Boss, a Cactus appears on the ceiling. It shoots homing needles. These deal 1 eighth of your health.
Healing Aura ♥ Despair Slime glows green, healing himself. You can stop the aura by vacuuming it. With this aura, you can heal yourself.
NOPES FOR DAYS Many NOPE Slime ferals come in and try to attack you. If you feed them, they will be on your side and (attempt to) attack Despair Slime.
Mini-Explosions This attack is similar to Zero Two's main attack from Kirby 64. He summons boom plorts that explode into mini plorts. You can absorb the Mini plorts to gain half the money you gain for normal Boom Plorts.
Dark Void Despair Slime summons a black hole. If you manage to withstand the black hole, you get a plort to damage the Despair Slime with, but if you don't you will have 1 hp left, only relying on the Healing Aura attack to heal yourself.
Tea Break ♥ Despair Slime lies down and does nothing but drink tea for the next 15 seconds.
TARRS! Despair Slime summons 5 Tarr Variants to attack you. If you manage to cure them, they will all be Hero Slimes, so they can attack Despair Slime

♥ = Non-Damaging
