Jack-o'-lantern

Jack-o'-lanterns with the faces of Bowser, Boo, and Shy Guy carved on them appear as course elements in Mario Kart Tour, exclusively during tours that occur around Halloween.

Jack-o'-lanterns appear in several sizes. Smaller ones typically lie on the track and can be knocked away by driving into them or hitting them with an item, growing back in the same spot after a while. Larger Jack-o'-lanterns are found on the sides of tracks or in the background, and, when hit, they make a bobbing movement while remaining in place. Like with festive trees and kadomatsu, interacting with a Jack-o'-lantern of any size awards the player bonus points, with the action being displayed as "Trick or treat!" Additionally, when hit, Jack-o'-lanterns emit a brief Boo-like chortle, with larger ones emitting said sound at a lower pitch than the small ones. Starting October 25, 2020, 06:00 UTC, interacting with a Jack-o'-lantern also gives drivers an event token.
