Ever alert

A sailor character with a large nose and glasses repeatedly shouts and clenches his fist while leaning over a railing in a blue, metallic interior. The scene cuts to a large man in an orange suit shouting angrily while a small yellow sponge looks on, then returns to the sailor, who is now shown with cracked eyes and a pained expression. The sequence ends with a shot of a dejected, injured man in a wheelchair in a sandy, underwater environment.
