Submerged Stint is the second Funky's Flights mission in the Game Boy Advance port of Donkey Kong Country 2. It can be played in Crocodile Cauldron. This mission has a ten-minute time limit that can be increased by picking up the clocks around the area.
In this mission, Diddy Kong must use the Gyrocopter's winch to bring a treasure chest to the end of the area. This mission has multiple ammo boxes lying around: if Diddy collects one, he gets the ammo depicted on the box. Three times during the mission, Diddy has to destroy a large crate blocking the path by shooting it. When Diddy goes underwater, the air meter starts decreasing. If he collects an air bubble, the air meter resets to 60 seconds. While underwater, Diddy moves and shoots slower. After Diddy navigates through the underwater section, Funky Kong can be found at the helipad. Diddy must drop the chest by Funky and then land to complete the mission.
