Leaf Guys are enemies in Mario & Luigi: Bowser's Inside Story. They are only fought directly in the Wiggler boss battle. They are Shy Guys in dark green cloaks, but can hover above the ground like Fly Guys, thanks to the leafy sprouts on their heads that act as propellers.
Two Leaf Guys will support Wiggler in battle by holding a giant turnip and dropping it on Bowser. If the player uses Bowser's inhale ability, the Leaf Guys will be swallowed by Bowser, and the turnip they were holding will drop onto Wiggler and make him vulnerable if he is red or damage him if he is yellow. Then the Leaf Guys face Mario and Luigi inside Bowser's stomach. The Leaf Guys only possess one attack, which is to fly at both of the Bros. together, who must counter their attack with Hammers. In another one of Wiggler's attacks, Wiggler will use a watering can to grow several plants. Wiggler will then harvest the plants and throw them at Bowser, but some of the plants are actually Leaf Guys. Bowser must retreat into his shell to avoid being hit by a falling Leaf Guy.
Leaf Guys also aid in the battle against the Tower of Yikk. They will carry bombs and drop them on Bowser. Occasionally, however, they may carry a Mushroom. Bowser can easily dispose of these enemies with fireballs.
