The Mushroom Genie
in Mario Party 3
“...Did you call, Master? I am the Mushroom Genie who lives in the magic lamp. Very well! I shall take you to the Millennium Star! Jump on my back! Hang on tight! Here we go!!! Mushroom-Kadabra!”
—Mushroom Genie, Mario Party 3
The Mushroom Genie is a magical entity first appearing in Mario Party 2. When a player uses a Magic Lamp, the Mushroom Genie appears and takes them to the board host, from whom a star can be purchased. He reappears in Mario Party 3, and also has a counterpart in this game: the female Mushroom Jeanie of the Lucky Lamp, who will instead change the star's location. His role was replaced by the Genie of the Lamp in Mario Party 4 and the Flutter Orb in Mario Party 5 onward.
The Mushroom Genie makes a small appearance in issue 27 of Super Mario-Kun. After getting attacked by a Thwomp, Mario rubs a Magic Lamp. Here, the genie is seen carrying Mario, Luigi, Yoshi, and Wario from falling to an evil face.
