Dry Bowser was racing around the Carnival Town on the Rocky Coaster race course, riding on the wooden tracks of the rollercoaster as he was testing out his Bone Rattler, with the skeletal reptile deciding to test out his driving skills in a different type of grand prix.
"This course is more curvy than most of the tracks I've raced on..." Dry Bowser stated as he entered into the mountain, going through the purple cavern as he noticed all the party skeletons celebrating as they released purple bats. "Perhaps there's a reason the grand prix I enter into isn't as... exciting as this one."
Dry Bowser then left the cavern, being right back out in the open as he noticed the creepy sun smiling down on him. Feeling disgusted, Dry Bowser decided to focus on jumping on the various ramps that were present, landing rough jumps as he went through another cavern, with him exiting as he noticed a rainbow road curving around as it lead into a cavern full of waterfalls. Dry Bowser felt his bones get wet, shaking his entire bony body as he continued to drift around the course, not letting the water get to him as he was focused on improving his skill.
