Help With Naming Elemental Mobs.

In my mod, Chaos & Calamity, I want to add "elemental spirit" type mobs to fill out the four elements, alongside the Blaze and Breeze, as well as boss versions of all four. I'm looking for help coming up with names for the water and earth spirits that still fit the naming convention of the Breeze and Blaze. The best I've come up with is the Boulder and the Brine. If you have any better ideas, please leave them below.
