Submarine Banjo

The Submarine is the transformation of Jolly Roger's Lagoon. It's controlled in the same fashion as the Talon Torpedo: turn it with the and propel it forward with. For combat, you can fire torpedoes at distant foes with and press  to unleash a Sonar Ping attack against closer enemies. The Submarine is the only way to get to the bottom of the Lockers Cavern and play the Submarine minigame. The Submarine can be used to fight Lord Woo Fak Fak, making it the only transformation (aside from Dragon Kazooie) able to fight a boss.

Submarine Banjo cannot warp onto land using the Warp Pads; however, through a possible oversight in the submarine's traversal range, it can be driven straight out of the water onto land. Simply backtrack through Atlantis towards the entrance in the bay, using the sonar ping to freeze Inky the octopus, and drive up the ramp in the bay onto dry land, allowing you to explore the town and surrounding areas as the sub. However, you can not get past the stairs, making Jolly's, Pawno's shop,Mumbo's Skull and the exit impossible to get to, but you can still access Turtleview Cave, Captain Blubber's waveracer shop, and the small pool where the pigs are. Strangely, even when on the surface the underwater theme will still play.

A model of the Submarine transformation appears in Banjo-Kazooie: Nuts & Bolts as an exhibit in Banjoland near the entrance.
