The battle arena has three rows of elevated platforms including the ground with smaller platforms mounted on the walls. Johnny's attacks include tilting his head on and charging at the player. Whisker's attacks include a ground pound that emits a shockwave upon landing which can be avoided by jumping, shooting his arms off like rockets that arc around and return to him and breathing out a powerful blast of flames that could stretch either reach a small distance in front of him or the entire platform range. The player can damage either Whisker or Johnny by simply jumping into them with Spin Jump/Axel Jump.
Whisker and Johnny have a combination attack which is indicated if Whisker stands still and seeming blocks all the player's attacks. After a while Johnny charges towards Whisker, Whisker will toss him with a lot of force such that he accelerates around the arena at high speeds. A spin of any sort is required to repel this. In addition to these devastating attacks, the player must be careful of a spiked wheel that appears on the ground during the fight. After a short delay, it will sweep along the platform length back and forth at fast speeds, damaging the player on contact. After intervals, the wheel will spawn at the next platform above and will repeat its movement (after it finishes its cycle with the top-most platform it will return to the ground level). The player should fight Whisker and Johnny on platforms that do not have a spiked wheel. The fight ends once the player depletes the health gauges of both Whisker and Johnny.
In normal difficulty, two rows will each have a spiked wheel at the same time.
