Giga Clubba is an optional hidden Clubba boss who appears in Crayon Mario 2: The Legend of the Time Flower. Mario and his partners encounter him during Chapter 7, although he is fought before or after the game is beaten. He is invincible at first by shielding himself at the start, but the shield can be removed by Windy's Gale Blow move, making him vulnerable to Mario's attacks. Defeating him in battle grants the player access to a room with a note in it. This note will give the player a code that, when inputted in the title screen, will allow the player to freely access any of the Mini Battles.
