What players call bosses are actually goo infected specimen of regular animals. The word 'boss' is made up by players as a short-hand. it even refers to different types of those infected creatures depending on which community you ask. So the environmental effect is actually there, it just can't be changed by players (yet). And i really hope that a successful fight against the goo does not reduce boss spawning in the future as it possibly should.
