The Thruster is an option originating from the Cannon Ball seen in Infiltrating the Airship, more specifically within the "Relentless Bounty Hunter"/"Rapidly Promoted Executive" pathways.
Infiltrating the Airship[]
Shortly after breaking into the airship with the help of his cannonball, Henry spots Reginald Copperbottom accompanied by Right Hand Man. The latter orders the leader of the Toppats to run to a safe place, claiming that the issue will be taken care of thereafter.
Deploying two thrusters, Henry flies to RHM. To his displeasure, the thrusters are very slow-moving, giving the second-in-command a chance to shoot one of them. The cannonball swiftly loses control, and crashes into a wall. This results in a fail.
Fail Message[]
Yunno, I really expected you to go faster with those thrusters.
