Tips: Invisible

To become invisible, you need an owner and a pico.
The owner must go into decor mode
Put the chair against the wall but put an empty space between the back and the wall.
The owner must stand behind the chair.

The person becoming invisible must sit on the chair. The owner will then click the UP arrow key.
After 5 seconds the person on the chair must click in front of them.
This will cause them to become invisible. ;) Easy, huh?
