Haltmann fan[conjectural title] is a stage hazard present at various points in Kirby: Planet Robobot. It is a large hovering machine with a rotary fan built in and has the Haltmann Works Company logo emblazoned on its side. Its only function is to remain in place and blow a continuous wind current in whichever direction the rotor is facing. This wind current will push Kirby with a continuous force that varies depending on the fan; some only mildly affect him, while others completely prevent him from passing. In addition, the Haltmann fan can push clouds of toxic gas around; both those that can harm Kirby, and those that he himself creates using the Poison Copy Ability.
The Haltmann fan cannot be destroyed, attacked, or directly interfered with in any way by Kirby or any other entity.
