Lifts (also known as elevators) can be found all across the various Creatures worlds. All Creatures games have a group of objects that take creatures up and down, frequently for hours on end. (C1 Norns in particular are noted for their fascination with lifts). Lifts are associated with a call buttons on each level. A lift can move when a creature or the Hand pushes either one of the call buttons or one of the movement buttons inside the lift.
In C1, lifts are a separate genus of objects. Pushing the lifts makes them go down, and pulling the lifts makes them go up. A C1 Elevator Fix is available for a problem where creatures sometimes get stuck in lifts when the lift stops moving.
