Up for sale is a 1981 Star Wars Yoda hard vinyl figure that works like the magic 8 ball.  He has liquid inside and a viewing window on the bottom.  Just shake Yoda and find the answer to your questions by reading the several sided die inside.  It looks like it has about 12 different answers.  This figure is approx. 5-1/2" tall and made of hard vinyl.  Yoda shows his age with dirt/staining and various spots of paint wear.  The dark fluid inside Yoda has stained the die, but the messages are still legible.  The die inside has small pieces broken off on the tips of some edges.
