Super Mario RPG players will get to Booster Pass after going through Moleville, the first area in the Moleville Region. Booster Pass is not a large area at all, but there are two very well-hidden treasure chests for Mario and the gang to find, which will hold helpful items that shouldn't be missed. If players have the Signal Ring equipped, the game will notify them of the hidden treasures, but, of course, this guide will show players exactly where to find them.
