I like the shells for some aggressive and tough battles, even some CPUs chase me (mostly in DS Palm Shore) and I had to fall off the stage when they come closer (they might fall off too!
) to 'protect' myself. Not just the shells appear however: The Lucky 7 gives the player 7 Red Shells instead of three!
