SOUL Types are exclusive to Glue Creatures and are a measurement of what the SOUL of a Glue Creature appears as and how exposed the SOUL is. There are many different types of SOULs, but there are three main categories:
Button: The SOUL is a round button-like appendage on the Glue Creature, and is mainly located in the center of the torso.
Hidden: The SOUL is within the physical body of the Glue Creature and cannot be seen normally.
Miscellaneous: The SOUL is located elsewhere on the Glue Creature's body, and can be seen normally. For example, a Glue Dragon's SOUL may be located to its tail spike (if applicable).
