- Not to be confused with Green Switch Palace.
The Green Switch is a Japan-exclusive e-Reader card that is used with Super Mario Advance 4: Super Mario Bros. 3. It was included in the Series 2 set of cards. It can be used only in World-e. The key art is light green and featured an outline of Toad.
Once this card gets scanned, the timer and music slow down for the first 50 counts, giving the player more time to complete a level. When 50 counts are past, the "coin" sound is played and the timer and music go back to their original speeds.
Makes the timer go slow!
