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 in 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 there is to go to 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, and there were watchtowers, 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.
"Driven to Tears" - Sentenced to 90 days in jail for littering, but was pardoned when SpongeBob admitted he was the litterbug, and he was sentenced instead. He was ticketed for running three red lights.
"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, but he was never seen being arrested.
"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.
