Things can't die, and they don't need to do anything. How do you know everything else that lives there isn't fine with it either?

[Bowser isn't as concerned with the other creatures, anyway, though he won't say that out loud. Not that he has a problem with them either, but between the Piranha Stubbies, griffons, and the fish, Bowser is more inclined to protect the Piranha Stubbies.]

My suggestion's to take the stuff we need, and leave everything else how it is.
