Spring Platform
Spring Platforms[1] are devices found in Donkey Kong Country: Tropical Freeze. They are composed of a broad wooden platform sustained by two large springs underneath, and float on water with pneumatic cushions
The Kongs are able to stay on a Spring Platform normally, but can also use it as a trampoline. Performing a Ground Pound onto the platform causes the springs underneath to compress, removing two side clamps that hold the platform in place, and bounce the characters high up. This allows them to access normally out-of-reach areas and items or grab onto Climbing Grass on the ceiling.
Spring Platforms are encountered in Mangrove Cove and Shipwreck Shore. Near the end of the latter level, there is a particular Spring Platform that begins rafting across water once Ground Pounded.
