Double Bob-ombs

The Double Bob-ombs are the special item of Shy Guy, Roy, Wario, Waluigi, Purple Koopa (Freerunning), Mario (Musician), Black Yoshi, Toadette (Explorer), Daisy (Sailor) and the Wario, Chain Chomp and Goomba Mii Racing Suits in Mario Kart Tour. When used, two Bob-ombs are deployed to orbit the player's kart. The player must then tap the screen to throw both Bob-ombs forward at once. When Double Bob-ombs+ is unlocked, an extra Bob-omb is added, allowing the player to throw three Bob-ombs instead of two.
