The Cage Lift is a device that is featured in PSA Mission 6: Questions for a Crab. It is located at Herbert's Base, and uses a series of pulleys and barrier to use hydraulic energy for lifting a cage that traps the player.
The basis of the Cage Lift is built from a water tap that is placed above a vertical gutter, that has a drainage hole on each one of its sides.
A metal pipe, which can be tilt to the left/ right, is placed just below the water tap. Once water flow from the water tap, the direction of the water is determined by the angle of the pipe: if its buttom part pointed to the right, the water will go to the right, and vice versa.
On the left side of the device, there is a water wheel, made of metal cans. If the water flow to the left, it will rotate the water wheel, and while spinning it will lift the cage- allowing the agent to get out.
Between the metal pipe and the water wheel there is a barrier, that can be lifted by placing a cargo on a small platform next to it, which, using a pulley, will lift the barrier.
How to solve it
|Spoiler warning: Plot and/or ending details follow.|
- The first step is to throw a Puffle O on the switch of the water tap (by selecting a Puffle O and then clicking the switch). The Puffle will follow it, and let the water flow. The water will flow to the right.
- As the water flows to the right, throw a Puffle O on the left side of the metal pipe. The puffle will jump on it, rotate the pipe and change the direction of the water flow to the right.
- As the barrier prevents the water from rotating the water wheel, throw a third Puffle O on the platform that is connected with a rope and a pulley to the barrier. The Puffle will jump on it and its weight will lift the barrier.
Now the watermill rotate the water wheel, and free the agent.

- Herbert is most likely the inventor of this device.
