Awkward Day At The Aquarium! We're All So Different

Nodoka and Chiyu keep reminding Hinata to keep their identities as Pretty Cure a secret, as she nearly lets it slip as her friends discuss the monster attacks. As they visit the town's aquarium, problems arise as Chiyu and Hinata's personalities clash with each other. But then they notice that Pegitan is missing, as he fled from the aquarium staff when they mistook him for one of their birds. While the trio search for him, Shindoine creates a Megabyogen and accidentally captures Pegitan amidst the attack. Upon arriving at the Megabyogen's location, Chiyu and Hinata see Pegitan and decide to take him back. Nodoka arrives as Shindoine releases Pegitan, and the three girls transform to battle and defeat the Megabyogen, freeing the Bubble Spirit trapped within it. Chiyu reprimands Hinata for being reckless and putting herself in danger, with Hinata apologizing as both girls reaffirm their friendship.
