4-Person Panel

A 4-Person Panel, also referred to as blue switch or 4-minion switch in Bowser's Castle, is an object in Mario & Luigi: Partners in Time. It is a panel found in areas throughout the game, and all party members must stand on it in order to open nearby gates. Blue Warp Pipes sporting the same four-square image as the 2-Person Panel also exist, and require all party members to stand on them in order to progress. The 4-Person Panel has a rarer yellow variation which functions similarly, except only either Mario and Luigi or Baby Mario and Baby Luigi need to stand on it in order to activate it.
