Blue Switch (card)

From the Super Mario Wiki
The Blue Switch card that triples the effect of 1-Up Mushrooms

The Blue Switch is a Japan-exclusive e-Reader card for use with Super Mario Advance 4: Super Mario Bros. 3. It was released in Series 1 in Japan.

Once it is scanned, all of the 1-Up Mushrooms in the game become 3-Up Moons. This feature allows Mario and Luigi to accumulate extra lives more easily.
