This is the any% TAS of Donkey Kong Country 2. The movie aims for overall fastest completion and doesn't give a flying banana about bonus rooms. Warp barrels are used whenever possible, meaning a large part of almost every stage in the first two worlds is skipped.

previous movie (5 minutes and 6.33 seconds to be exact) thanks to greatly increased precision and a multitude of new tricks, all of which are explained in detail in the author's lengthy
