Beastly Burrow (Pikmin: New World)
From Pikmin Fanon
The first dungeon of the Enveloping Garden. It is a rather short, six-floor dungeon with very few enemies. It is the very first dungeon to appear in the game with a boss. It is mainly a tutorial dungeon with several enemies and not much cargo. Getting there requires beating a creeping chrysanthemum and going through a clearing filled with runbulbs and dwarf red bulborbs, but otherwise is not that challenging to access at all.
