The start of the stage has spiked balls rolling by. Descend and you’ll see some steam come from the cracks. Ride on a speed bike and you’ll battle against various species as you go along. After a long path, you’ll battle against a Big Octo with a spike helmet. The Big Octo will unleash a barrage of energy balls. Aim for the glowing area of the helmet and after you defeat the Big Octo, the adventure will continue on the water with the same species you same before. After a long ride, descend to the next section, but watch for steam emerging from the cracks. After defeating a few shielded gunners, ride the bubbles to ascend, but watch for the spikes. You might find the “O” letter as you go along. Once you see a duo of shielded gunners, turn right and you’ll next see spiked balls on chains. The next section features cloud drones dropping skull fragments. Enter the cap doors and you’ll battle against Wave Man. Wave Man will jump up and throw some tridents. Use the Napalm Shoot to deal more damage. Defeat Wave Man and you’ll receive the Triple Wave.
