Double Bob-ombs

The Double Bob-ombs are the special item of Wario, Waluigi, Shy Guy, Roy, Mario (Musician), Black Yoshi and Toadette (Explorer) 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.
