Leaf Guys are enemies and a subspecies of Fly Guys that appear in Mario & Luigi: Bowser's Inside Story but only on the Boss fight against Wiggler. Leaf Guys are green Fly Guys with leaves as their propellers.

In battle, two Leaf Guys will support Wiggler by holding a giant turnip and dropping it on Bowser. The player must inhale the Fly Guys as Bowser, leaving the turnip falling down into Wiggler, leaving him vulnerable if he is red or damage him if Wiggler is yellow. Then Mario and Luigi fight the Fly Guys inside Bowser's Body. They have only one attack, which is flying at both of the Bros., who must counter the attack with their hammers. In another one of Wiggler's attacks, he will grab a watering can to grow several plants. Then he will grab them and throw them at Bowser, but some of the plants are Leaf Guys. Bowser must retreat into his shell to avoid getting hit by a Leaf Guy.

Leaf Guys appear one final time in the game in the fight against the Tower of Yikk. They will aid the tower by holding bombs and dropping them at Bowser if he takes too long to dispose of them with fireballs. Sometimes, they may carry Mushrooms.
