Lockjaw's Locker is the fourth level of Donkey Kong Country 2: Diddy's Kong Quest, and is located within the Gangplank Galleon.
This is the first underwater level of the game, which takes place in the ship's flooded cargo hold. Similar to Coral Capers of the original Donkey Kong Country, the Kongs will discover Enguarde (at two separate points), as well as aquatic foes Floatsams, Lockjaws and Shuris. Klomps also appear. Enguarde is incredibly useful throughout this level, as he is needed to enter a bonus area, and he can take out enemies.
Despite the name of the level, the Lockjaws play no major role in the level.
