Mutated Mush
From IdleOn MMO Wiki
To summon this boss, take 
Toxic Sludge or 
Radioactive Waste to the Spaceway Raceway (Purp Mushroom map). On the top platform there are 1 or more mushrooms growing out of the ground. Drop the barrel on the mushrooms, this will spawn as many Mutated Mushes as there were mushrooms. The fight is similar to Dr Defecaus, but more HP and an additional projectile, similar to Amarok's Fireball.
After using up the mushrooms, you have to wait a minimum of 4 days for the next one to spawn. Boss spawns will increase according to the table below. The days are the total waiting days, not cumulative. It only counts days when you log in on at least one character.
Mutated Mush also appears in the 15th wave of the Astro Colosseum.
