Crabs “pee” (excrete waste).

SpongeBob SquarePants wears a red and blue mechanical head装置 with a large light, his eyes glowing red as he peers over a wooden barrel with a determined expression. The scene cuts to a close-up of a red crab, likely Mr. Krabs, with a wide-open mouth and a look of intense hunger, holding a hamburger in one claw while a white pole or stick is stuck in his mouth.
