Boo Spaces are spaces that appear exclusively on the Haunted Trail board in Mario Party 10, where thirteen of these spaces appear. The spaces are round and white with a Boo's mouth on them, similar to Boo's various Emblems. The spaces activate a Boo Change event, where a roulette wheel will decide which player the Boo will haunt. The Boo will steal five Mini Stars from them every turn until the Boo either a wheel spin causes the Boo to haunt another character or is scared off by a Streetlight. Only the three characters who do not currently have the Boo appear on the wheel, so the currently haunted character cannot have a prolonged time with the Boo. Any character can activate the event, whether they are currently haunted or not.
