Mario claps and cheers when Casper lands, just out of reflex. "Oh, that was'a good one!!!" He abandons his search for debris to stem the flow of water, which is great, becuase they're in a hallway that leads to a bunch of personal suites, so he'd have to go in one if he wanted to find something.

"Climb, eh? I guess the water would make that hard." Or the wall-slime, maybe.
