Jet Pack is a skill that can be given to a lemming in Lemmings 2: The Tribes. Jet Packers float above the ground and only move with aid of the Fan tool. Which can be used to push the lemming around, but the lemming will sink downwards unless the fan is used constantly to push it from below. There is a time limit for the Jet Pack fuel of about 10 seconds. A lemming with a jet pack can survive a long fall, and so this skill can be used as a one-time floater.
