Cannon Space (Mario Party 10)
From the Super Mario Wiki
Cannon Spaces are spaces that first appear in Mario Party 10, only on the board Airship Central. If the player lands on one, they get to fire cannonballs at Bowser's airship, damaging it; once the airship is hit by ten cannonballs, the last player to land on a Cannon Space is awarded ten Mini Stars before everyone continues to the Homestretch. Sixteen of these spaces appear in the board, all of them being on a circular stretch of the board just before the Homestretch. Of those sixteen, twelve fire two cannonballs each, and the remaining four fire four cannonballs each.
