The Ocean's Mood - S2.E11

While sinking into the ocean, Kyururu has a dream where he once again encounters Parotia and Lophornia, who warns him of an impending crisis. He is then rescued by Dolphin and Sea Lion, who inform everyone about the Ceruleans emerging from Kyururu's drawings. Just then, a giant boat-shaped Cerulean attacks the hotel, causing Ceruleum to come into contact with the drawing Kyururu gave Pigeon and spawn Ceruleans of all the Friends drawn on it.
