Episode Title:
Mysterious Girls? The Bequeathed Legendary Key!.
Episode Description:
As the girls lament losing their keys, Pafu has a dream and starts sensing the scent of the keys. While trying to pursue Pafu, Haruka, Minami, and Kirara end up following some mysterious girls to a hidden garden, where they are holding a tea party. Meanwhile, Lock uses the captured Dress-Up Keys to draw despair from the dreams stored inside. When a giant Zetsuborg comes to attack the girls, Haruka and the others decide to face the enemy despite being unable to transform. Seeing their strengths, the three other girls give them temporary Dress-Up Keys, allowing them to once again transform and defeat the Zetsuborg. Afterwards, the three other girls reveal themselves to be the previous Princess Pretty cures, who had pulled the girls into their dreams, encouraging the girls to stand up to the power of darkness before leaving them with the Sakura, Coral, and Galaxy Dress-Up Keys. Meanwhile, Lock uses the despair he had gathered to transform Hope Kingdom's castle into a giant Zetsuborg, which he sends to attack the human world.
