Leaf

The Leaf is an item appearing in Fleeing the Complex during the "Ghost Inmate" route. It is a reference to the Super Leaf power-up from Super Mario Bros. 3.

Henry can choose this item when he reaches the docks at the foot of the complex. When chosen, the leaf gives Henry a raccoon tail and ears, which he can use to fly over two guards without being noticed. He thus reaches the dock with the S.S. Annie, a Dinghy and a Rocket.

Trivia

 * The Leaf is a reference to the Super/Tanooki Leaf from the Super Mario series.
 * Upon consuming the power-up, the player will be able to fly for a limited duration. However, unlike in the original games, Henry loses the power-up upon landing on the ground.
 * By clicking where Henry will land, he will roll safely, instead of collapsing, leading to the achievement, Nailed It.
