Once, when the skulk was trying to take over the land, a humble skeleton found a rock. The rock was green, and covered in moss. He picked it up, and a bright flash blinded the cavity where his eyes once were. When he could see again, he was covered in plants, and had some new powers. Now, wherever he shot an arrow, the place where it landed would become overrun with plants. When shot on skulk, the skulk was transformed into regular materials, like grass and dirt, or what ever it was when it was made into skulk.
