Want to de-gnome the garden? The above image would be the instructions. You'll have around 90 seconds to throw gnomes out. You don't need to swing your mouse to swing the gnome; just click the head of the gnome that will appear on the bush and the rest will follow.
I had a hard time realizing it but you need to throw the gnome to the RIGHT side. Bonus if you can throw it past the cut trunk. :)
