You don't get a real volcano lair, which might be dark and cramped, and might also be subject to nasty dangerous gases and at risk from lava. You get an optimized meme-volcano lair which is roomy, well-lit, mostly safe, only adds drama when it improves the story, and is lavishly appointed.

In the same spirit, cats and girls are capable of being annoying, though in rather different ways. Catgirls are only annoying if it's cute.
