I would really like to see a link between the water sprinklers and a water trough. In OSI we had something similar with a water pitcher called, "The Endless Decanter of Water" which gave us the ability to link the pitcher to the water trough, thereby never needing to refill the pitcher while we watered our plants. Right now we're using a sprinkler-filling container which empties quickly, as does the sprinklers.
Makes kind of real life sense to have a link from our sprinklers to a water source, like a virtual pipe leading from one to the other.
By the way, the decanter was gotten in a very funny way. You had to toss a water filled pitcher at a live water elemental. You had a chance to get the decanter in your pack. Water elementals could only be used once for this purpose. If you didn't get it the first time you had to find another water elemental and try again.
