The Green switch is one of the 4 colored switches found in Super Mario World. When the Green Switch is stomped on, all the Green dotted blocks in the game will turn into Green solid ! blocks. The Green Switch is named "Green Switch Palace" in Super Mario World. When the level is entered it will look much like the bonus game like in the other palaces. It should also be noted that whenever the Green Switch Block is hit a feather will always come out.
