Rolling Ball

From the Super Mario Wiki

Rolling Ball is a mini-game in Super Mario Galaxy. Mario rides on a huge capsule which contains a Star, avoiding wandering enemies and voids, to clear the game putting the orb into a hole in order to earn the star contained in the orb. The player can find this mini-game in the Rolling Green Galaxy, Melty Molten Galaxy and Rolling Gizmo Galaxy.

[edit] Trivia

• The Rolling Ball minigame is similar to the Super Monkey Ball series of games, especially the Wii one, since the player can jump in that one.
