A tiny dynamo!
Wind it up and set it free on the table. Let it march away, hop over small obstacles, tumble around, roll over and keep going at it. Try winding PEA up, and rolling it gently on a table like dice; more often than not, PEA tumbles to its feet and cruises on. PEA may behave like a tough guy, but it is rather delicate, so, please be nice with it. Enjoy.
