Tentacles.

He is best friends with SpongeBob and often encourages activities that get the two into trouble, especially when Squidward Tentacles is involved. He owns PatriK's Bar, SpongeBob's bar of choice, throughout the course of the series. Patrick holds various short-term jobs as the storyline of each episode requires.

Whenever any aquatic creatures enter her air-filled dome, they must wear helmets filled with water to breathe.
