Koopa Kid Orb
From the Super Mario Wiki
The Koopa Kid Orb (known as Mini-Bowser Orb in PAL regions) is a special orb found only in Mario Party 7. When a player gets it, a Koopa Kid comes and uses it instantly, to create a new Koopa Kid Space. There are two ways of getting a Koopa Kid Orb: from the Orb Space, or from Bowser's Shop after he replaces an Orb Shop. Since Koopa Kid uses the Orb, it will not count toward the amount of Orbs the player has used when obtaining the Orb Star.
