Blue Green Switch

The Blue Green Switch is an e-Reader card for use with Super Mario Advance 4: Super Mario Bros. 3. It was included in the Series 2 set of cards. Although technically a Power-Up card, it was labelled as a "Game Level" card.

Once scanned, Vegetables will appear all throughout the main game, which Mario can pluck from the ground and throw at various enemies, just like in Super Mario Bros. 2.
