Episode Title:
Summer! Beach! Homework!
Episode Description:
For their independent research project, the Cures, along with Satoru, go to Animal Town's beach to study sea turtles and how they lay their eggs. However, since sea turtles lay their eggs at night, they decide to spend the day at the beach until then. When a sea turtle Garugaru attacks, it takes Lillian with it as she clings to its back. As the Cures go after it, Yuki is initially afraid of being without Mayu, but overcomes her fear in order to save her and protect the sea turtle eggs, which are in danger of not hatching due to the cold temperature. After Wonderful and Friendy purify the Garugaru with Friend Liberale and return it to Niko Garden, the Cures and Satoru watch a sea turtle lay its eggs.
