Any Kayna headcanons?
Hmmm... let me think...
-Kaynas CAN be formed from different kinds of minerals/rocks, similar to Jeeodes! Though, these are typically igneous rocks.
-On the outside, Kaynas are actually a bit cooler to the touch than you may think. Of course, they're still warm, but not scalding hot.
-The magma inside of a Kayna's stomach acts like a weird form of stomach acid. In fact, Kaynas are the few species of monsters to have unique stomach acid/digestive properties. (These include: Wubbox [they have no digestive system, but transport the food they swallow into another dimension], Riffs [stronger acid than usual, developed purely because of the fact that they eat almost anything they find on the ground], and a few others that I cannot think of at the moment...]
