Border Patrol is the fourth episode of The Algae's Always Greener. In this episode, Squidward is arrested by the Bikini Bottom Customs and Border Protection Agency because when he returned to Bikini Bottom from Squidville at the end of the original Season 2 episode, he forgot to refile his Bikini Bottom residency status that was automatically taken from him when he moved to Squidville, eventually causing an intense political debate, even if almost everyone in Bikini Bottom hates Squidward.
