Clouds

Clouds are floating items that do not need tiles. If activated, they rain down as Puddles, the lowest tier Water item. Bigger clouds can rain more, until they deplete.

Steam comes from non-renewable Steam Wrecks. If they have two free tiles around them, they periodically produce Steam. The only know n way to get Steam into home base again, is to buy it for rubies from map rewards. The alchemist can ask for Steam.

You get Clouds by merging Steam or by activating Balloons that are ready to release their gathered clouds.
