Kohatora, literally meaning "stone of life" in the language of The Ancients, are precious jade stones. They are all sculpted to represent a sacred creature.
Finding a Kohatora allows the player to unlock a rare and useful creature in exchange of stars. The player has to find three Kohatora of the same type to unlock its associated creature, the more Kahotora the player finds the less stars it costs to unlock the Kohatora's creature.
Kothatora is found by completing basic puzzles by blocking off water streams using rocks.
