	That's Cresent Valley High School's new machine: Card Shark
	Card Shark was seriously damaged on the first day. They broke a crank sprocket. They lost an axle nut, and replaced it with a vice grip. And they broke open their plastic pontoons [not shown].
	To replace the broken pontoons on Card Shark, the boys from Cresent Valley High School used part of the foam pontoons I had donated. These were the pontoons on Platypus Rex and Time Rex years ago.
