Nature Type companions are mostly found in the Lush Forest and Misty Glen due to the area's high density of forestry. Appearances vary depending on the species, but mainly mimic greens, browns, and flowers of the forest. With the change to this type, companions require more water and sleep. However, a Nature Type Kasatarian that properly satisfies its needs can easily live longer than average.
To change into a Nature Type, a companion must cover themselves in ebb enchanted soil, without disturbing the area's growth. This dirt can be hard to find, since it can be difficult to find a site of rapid growth (caused by ebb), and even more difficult to find one that still has a lot of ebb present. The Lush Forest is the largest example of woods that was rapidly grown by ebb, however it has long since left and the soil cannot transform a companion.
Nature Type companions never stop growing. The older they become, more of their nature appearances will cover their bodies. The Nature Type companion images depict the average adult appearances.
The Water Type companions take on unique appearances that help them adapt to life in the water. They become much faster swimmers and have increased sensitivity to help them "see" farther in the water. However, they cannot actually breathe underwater. Their adaptation allows them to hold their breath for much longer periods than their other Types, much like the Galeodo.
To change into a Water Type, one must find and drink special ebb enchanted water. Currently, it is unknown what exactly causes small pools of water to become ebb enchanted, but tales of Kasarians who travel the seas for months at a time report seeing the light of ebb fleeing into various waterlogged flotsam, or simply attaching to the water itself, making it glow - thus enchanting the water.
Living underwater introduces a myriad of new problems, especially if a Kasarian was not born a Water Type. For example, not only does land travel become extremely difficult, and their blackened eyes become sensitive to unfiltered light on land, but communication is also a challenge. Water Types have to rely on specific motions to express their thoughts, but usually try to find an air pocket in a cave, or they swim to the surface to talk.
