Decorations are purely cosmetic, they provide no income, neither coin or mineral. Some decorations can be clicked on (the swing, the treadmill, the elastic bed and the horsie) and a Starling will go and play on the decoration. Decorations can also be used as a wall, not being able to be destroyed and covering more ground it is a useful way to use them. A difference to the wall also though is the price. The cheapest decoration is the swing for 2000 coins, and even that is quite a difference to a normal wall. Whilst walls come back after being destroyed, decorations cannot actually be destroyed!
The Swing is a part of the Decorations, Starlings can play on it.
"A great way for Starlings to exercise!"
The Elastic BedEdit
"It almost like that Starling is flying! Yo-hoo!"
The Elastic Bed is a part of the Decorations, Starlings can play on it.
