While searching for the Headmaster to get information about Ha-chan, Mirai and Riko hear a rumor about a magic door hidden in a tree and decide to investigate. After facing living branches and giant caterpillars, the girls arrive at the fabled door, but are suddenly confronted by Batty who uses the combined powers from Spalda and Gamets' wands to transform himself into a more powerful form. Once again, Ha-chan manages to call forth power from the Linkle Smarthon, gaining support from the forest and allowing the Cures to beat Batty back. After receiving an Amethyst Linkle Stone and eating its fruit, Ha-chan goes to sleep inside the Linkle Smarthon, which unlocks the magic door for the girls.
