Dan Chovie and Ann Chovie, otherwise known as the Chovie Twins are two twin anchovies who attend Freshwater High.
They have lots of school spirit and often act strange.
They were once about to be signed by Jocktopus, and when Jocktopus signed them, they cheered ("Underwater Boy"). Oscar once rode Dan and Ann's car, only to be uncomfortable because of Ann saying that she and Dan have matching birthmarks ("Riding in Cars with Fish"). When Bea and Milo tried to help Oscar find a club, they ran into the agriculture club, which they decided not to join once they saw Dan and Ann Chovie milk a cow ("We've Got Fish Spirit").
When Milo was about to play his kazoo, even though Lonnie and the marching band banned him from playing it, Dan and Ann told him that the marching band sabotaged their recording session for their next album called, "The Chovies: Together Forever ("Banned Band").
