Right next to where the beach is, there is a large cave, with the entrance marked by two fallen palm trees in an X pattern. Inside, it is very light because of a giant bonfire in the middle of the cave and the fact that there are light Tocous living here. There are puddles around that look deeper than they appear, and the largest is big enough for two Tocous to lay down in.
This is the house of Mitoku and Wolfgang's family.
