Watering Can
This is one of the cards that is in each player's starting hand.
There are also WATERING CAN cards without stars on them that are shuffled into the STORE DECK.
When you play this, turn any one Pile so that its GRASS side is face-up.
Any cards on top of a Pile stay there when that Pile turns from DIRT to GRASS (or vice versa.)
If the Pile that you choose is already GRASS, nothing happens.
If you're feeling generous, you can use this to turn a Pile in another player's YARD to GRASS.
