Secret Specs

The Secret Specs is a special equippable accessory item received from the Starbeans Cafe, the only Starbeans Cafe item exclusive to the Mario & Luigi: Superstar Saga + Bowser's Minions remake. It replaces the Power Grip from Mario & Luigi: Superstar Saga, as Mario and Luigi can now hold their hammers indefinitely while defending. This item is the fifth Special Item Mario and Luigi receive from Professor E. Gadd after they brew a fifth unique blend that has not been made before. While a brother equips the item, the player can see potential Hidden Blocks prior to when they are hit.

The Secret Specs sprite is designed after the Virtual Boy.
