The Donkey Kong Bananza Divide choice forces you to pick between the branching paths of the frigid Freezer Path and the tropical Forest Path. Your decision here doesn't really matter a whole lot as you must eventually visit both layers anyway, so you won't miss out on anything in Donkey Kong Bananza.

Bananza comes from the same internal team at Nintendo that developed Super Mario Odyssey, which is exemplified by its storytelling that prioritizes charm and good vibes over lore and dialogue.
