Prop

Prop is an option in Completing the Mission during the "Cleaned 'em Out" pathway.

Henry can try to use the prop to sneak on board the Toppat Train unnoticed. This results in a fail when one of the Toppat members loading the train burns the prop to test if it was fake, killing Henry Stickmin by burning him into ashes.

Fail Message
Well, fire IS the best way to test for fake props.
