Secret Box is an item in Mario & Luigi: Dream Team. It is a purple box with a white ? on its cover. When used, it inflicts a random badge effect on Mario, Luigi, enemies, or everyone in the battlefield. It acts much like a Mystery Box from the Paper Mario series. The effect of Secret Box is absolutely unpredictable. It can do things from healing Mario and/or Luigi, causing damage on enemies, giving all on the battlefield a random status effect, or even KO all or some fighters in the battlefield at once.
