The Bowser Lab is a location in Mario Party Advance. It is found in the Jungle Area of Shroom City, but it can only be accessed through the Pipe House's purple pipe. It has a teal motif with purple accents; the tiles and the glass in the background are tinted teal, while the laboratory equipment is coloured purple. A few flasks containing colourful liquids are scattered around, and one piece of equipment contains a large tube with green liquid consistently bubbling through it. Bowser and Koopa Kid create their experiments here, which includes Naval Piranha and Huffin' Puffin. Both of them are housed here as well. Naval Piranha must also be fought for the Bowserstein! quest, which pits the player against Bowser's creation at the laboratory to win a Duel minigame, Koopa Kurl. Once Naval Piranha is defeated, Bowser admits defeat himself and awards the player the aforementioned minigame.
