Learning from Lolo that there is a Princess Pen on Lala's home planet of Saman, the girls begin heading there but are unable to warp all the way due to Fuwa being too tired. Needing to rest for the night, Hikaru decides to hold a pajama party with everyone. While getting to learn about each other during the party, they discover an alien named Yanyan has snuck aboard. Kappard attempts to use Yanyan's anger to power his weapon, but the Cures manage to defeat him. With the rocket too damaged to warp, Yanyan offers to take the girls to her planet to repair it.
