Off to the left of the Air Ball drop game is a ramp that leads up to a cracked glass panel covering an entry way. Reptile Rush up the ramp to break the glass and enter through a series of lit-up dance floor rooms where there will be a ton of enemies.
The mobs of Cashino Corplets will continue to spawn no matter how many you take down, so don’t spend too much time fighting them.
Just clear whatever gets in your way, and start Reptile Rushing through the next cracked door panel where you’ll enter a room with a hydraulic ramp that will move up and down. This quadrant and a couple of areas after it will have some tricky ramp gaps that will require precision and timing with your roll dashes; get through all of the rooms to snag eight tokens at the end of the mini-course.
