I've worked my way through Alphadawg's tutorial over the last few days, and I've gotten everything to work, except for one little glitch that has me stumped.

When I create a dungeon entrance that appears under a pond that disappears from blowing the whistle, the color of the water doesn't change from blue to sand. The staircase dungeon entrance appears and functions properly, and I can walk across the water to get to the staircase, but the water is still blue.

I've checked under the Secret combos, but I can't find anything for the whistle. Is there a special set of water combo tiles I should use for disappearing water?

I'm using 2.10 (Build 0) of ZV and ZQ, on a Win XP machine.
