Category talk:Volcanic areas

The category says this article is for areas in the Mario series with lava, but it already includes places outside of the series, so shouldn't it say Mario, Donkey Kong, Yoshi, etc. series?

Castles
Why are castles included in the list? They are not volcanic. Even though they are full of lava, they do not have some "volcanic" elements, such as rising lava (there are a few exceptions), lava geysers, and poison fog. CBFan 5
