Bowserstein!

Bowserstein! is a quest in Mario Party Advance.
==In Mario Party Advance==
Bowserstein! takes place at Bowser Lab, where it begins if the player agrees to challenge Bowser and Koopa Kid. Bowser explains that he built "the ultimate monster" in hopes of winning against the player. The player is given the option to select either the "scary" monster or the "VERY scary" monster. The "scary" monster is the correct option, as selecting it reveals Naval Piranha, whom the player has to challenge in Koopa Kurl. However, the "VERY scary" monster is actually a Huffin Puffin, which harmlessly walks away, leaving Bowser embarrassed and forcing the player to restart. When Naval Piranha is defeated, Bowser admits defeat and gives the player the Magic Lamp Gaddget as a reward. Additionally, winning also unlocks the minigame Koopa Kurl.
