Daisy is only playable in the minigame "Daisy's Rodeo!". In order to win, you need to press the right buttons to stay on the mechanical Bowser's back. If you press the wrong buttons too many times Daisy will fly off and the game will be lost. While this game was released after Mario Party 4 and her official artwork for the game is seen on the card, Daisy's design in the minigame is her design in Mario Party 3.
Winning the minigame will give you the Daisy card which features her Mario Party 4 artwork.
☀ Mario Party-e is the only Mario game in which Daisy is a playable character and Peach isn't.
☀ This is Daisy's first and only appearance on the GBA.
