The Bikini Bottom Police Department (BBPD) is the main law enforcement entity in Bikini Bottom. This includes officers, wardens, prison guards, SWAT Team, and riot guards. Their headquarters is the Police Station. It first appears in the episode "Hall Monitor."
The Bikini Bottom Police Department has established multiple locations to base their operations, as well as places to contain offenders of the law. However, in many cases, it is unreasonably stricter than in real life.
The station is where the cops stay and receive calls for crimes, which is seen in "Life of Crime." They have a dispatcher unit somewhere in a different building of Bikini Bottom as well.
Inferno Island is a high-security prison, located in the middle of a body of water. The only way to get to it is to go there from the dock-yard, on a metal boat, to make sure there are no possible ways for prisoners to escape and swim to shore. The island is very harsh and the prisoners must sleep on hard beds with flat pillows.
Inferno Island is much like Alcatraz Island, a prison island from the early-to-mid 1900s that was strangely abandoned. Alcatraz was near land, had jagged rocks around it, and prisoners were transported to it by boat. The beds were hard, there were watch towers, much like Inferno Island.
"Party Pooper Pants" - Arrested apparently because he didn't invite the police to his party and spent a night behind bars in a bunny outfit. The initial reason was for attempting to break into his own house.
"Good Ol' Whatshisname" - Arrested for stealing What Zit Tooya's wallet and resisting arrest, as well as sprinting through a stop sign to escape with the wallet. He wasn't pulled over for committing an actual traffic violation until "Boating Buddies" (see below).
"Patty Caper" - Arrested for, ironically, stealing the secret ingredient to the secret formula (to avoid paying).
"Growth Spout" - Cited for attempting to steal Mrs. Puff's Peanut Wormss from her garden, thinking they were peanuts he was going to take to his overly hungry daughter Pearl (she was having, hence the title, a "growth spout"), but he was never seen being arrested.
"Goo Goo Gas" - Arrested for turning Mr. Krabs into a baby.
"Krabby Road" - Arrested for trying to steal the Krabby Patty Secret formula, then for breaking out of jail to steal it again.
"Sweet and Sour Squid" - Arrested when the police see him running around with Squidward's clairinet and assume he was the one causing the "musical disturbance" that many Bikini Bottom citizens have complained about when it was actually Squidward. When he was put in the police boat, he exclaimed "Karen!!! Help!!!". Strangley, the policeman tilted Plankton's head forward and said "Watch your head" when Plankton had plenty of room fitting in the car due to his small stature.
"Fiasco!" - Arrested for stealing a piece of famous artwork.
"Jailbreak!" - Originally arrested for an unknown reason and, at the end, was arrested for escaping prison/trying to steal the formula.
"Oral Report" - Arrested due to the fact her student, SpongeBob, was out of control and was under her responsibility.
"Patrick-Man!" - Arrested for attempting to steal a boat. This is false because Patrick Man thought she was trying to steal the boat (when she was actually trying to help the man get out of the boat) but she was charged with a felony anyway.
"Bumper to Bumper" - Arrested for crossing the county line, thus violating her parole.
