The Adult Bleech is a creature in the Keen 4 mod The Terror from Outer Space by Dr. Colossus. This is probably the most dangerous Bleech Type on Phaelox. The main form of attack is spitting large acidballs about the area. These stay on the ground for a few seconds before extinguishing. If Keen comes into contact with these projectiles he is killed.
