Two small, thin fish run in place on either side of a large, arched blue doorway with a seashell emblem, while a crowd of various fish watches from a balcony above; the scene cuts to a cloud-filled sky, then to a muscular man with blue hair and a determined expression standing in the doorway, his body suddenly expanding and distorting as his face changes to a different character's, all set against the backdrop of the underwater stadium.
