PRUI (PRONOUNCED PROO-ee)
The Prui is a gentle, friendly creature that grows.
All girls mill about with their eyes closed.
When you bump into someone, ask "Prui?"
If the other girl answers "Prui?" you have not found the Prui.
The referee whispers Prui to one of the players.
Since the Prui can see but cannot talk, that player opens her eyes.
When someone bumps into her and asks "Prui?" she does not answer;
they have found the Prui!
That player must find the end of the Prui so she can join it.
She may open her eyes once she joins hands with the last person of the Prui.
The line of girls will become long and it may take some time for the last players
to find the end and become part of the Prui.
