Helicopter Hat

Helicopter Hat is an option in Completing the Mission during the "Toppat Civil Warfare" pathway.

After Henry Stickmin is dethroned as Toppat Clan leader and forced to jump out of the Airship, he pretends to go along with it all and jumps, but secretly saves himself with a propeller hidden in his hat. He flies back to the Airship, and crashes into the brig. This results in a success.
