Cheese

Cheese is an option in Stealing the Diamond during the "Unseen Burglar" pathway, along with the Cannon and the Plank.

Upon selection, Henry eats the cheese. With a satisfied smile he looks around the room. This results in a fail as no progress has been made.

Wha-w... Why? ...Seriously?...?

Trivia

 * Cheese is one of the seven options in the series that doesn't do anything to Henry or his team, the others being Controller+Wings, Melt Ray, Bridge, Hack (CtM), Hot Knife and Retroglove.
 * This might be a reference to the nursery rhyme "The Farmer in the Dell" and its final line "The cheese stands alone."
