Submarine Banjo

Submarine Banjo is the transformation of Jolly Roger's Lagoon in Banjo-Tooie.

Submarine Banjo is controlled in the same fashion as the Talon Torpedo, by using the and advancing with. Submarine Banjo can fire torpedoes with, or press to use a Sonar Ping attack against closer enemies. The Sonar Ping can also freeze Inkies in lieu of Ice Eggs.

Submarine Banjo moves faster than normal Banjo does, and controls more easily underwater. It is also able to resist the stronger underwater pressure found at the bottom of the Lockers Cavern, making it the only way to play Grunty's Submarine Challenge. 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. This gives the player an advantage due to the faster and easier movement underwater, and the homing function and unlimited supplies of torpedoes.

Submarine Banjo has infinite oxygen, although this aspect of the transformation is only relevant if the Oxygenate Water spell hasn't been used.

Submarine Banjo cannot directly warp onto land using the Warp Pads. While it can be driven out of the water and onto land by way of the entrance to the bay, the submarine's movement is very limited on dry land, being unable to jump or control efficiently.

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