The SWAT team is a unit of Bikini Bottom's protection.
They have blue jackets, white helmets with a face guard, and brown pants. They usually have weapons in hand.
Some units are specialized in riot control, and others are in the K9 unit use guard worms. Security units are in charge of delivering a top secret item like the Krabby Patty Secret Formula in "Patty Caper." In "Banned in Bikini Bottom," a squadron of units was seen clearing out the banned Krabby Patties.
In "Fungus Among Us," there were special units called hazmat physicians. If a target happens to be in need of quarantine, a hazmat physician assists the SWAT Team in retrieving it.
