Which enemies are not consumed by the protozoid slimes, given the chance, in Duke Nukem 3D
From the Duke Nukem Wiki
The Protozoid Slimer will attack any weaker being close to it. That is, it will attack and "consume" Assault Troopers, Assault Captains, Pig Cops, Assault Enforcers and Protector Drones. It will do nothing to any other enemy, and it will not purposely go for any of those enemies (it will only try to attack the player).
