Go inside the Tret tree. To get to the entrance, there are vines going around his face. Solve the puzzles and get through the little mazes until you reach a room with a Psyenergy Stone and a chest. It is on level 4 of the tree. You may get those if desired. In that same room is a vine to get out. Climb it to get to another room (level 5). In that room, there is an entrance at the bottom. Go there, and follow the branches until you get to another vine going to another branch. Climb the vine and follow the branch. One of the branches leads to a room, level 6, with a chest. That same room is the one used to get to Tret (follow the path to the middle leaf, then jump off it. Jump back to it to fall through and end up at the bottom of the tree. There you will find Tret). You will finally see a final branch. Follow it and at the end is Breeze. You must battle him to use him.
