19

At the beach, Retasu encounters Iruka, who is bullied for her inability to swim despite her name meaning dolphin. Retasu offers support, but Iruka later reveals she can swim but fears water. When Retasu jumps in to encourage her, she nearly drowns, shaking Iruka's confidence. The next day, aliens attack the beach with chimera animas and summon a storm. During the battle, a boy from the previous day falls into the water. Iruka dives in to save him, prompting Mew Lettuce to follow. Struggling to swim, Mew Lettuce's legs transform into a porpoise tail, allowing her to navigate the water easily and rescue both children from the danger.
