"WHO'S that trip-trop-tromping on my bridge?!" hollers Clarence, the troll living under the bridge. The Three Billy Goats Gruff is a marionette romp in which three brothers "get the goat" of this green troll, whose eyes light up in his futile attempts to intimidate his intruders, as they try to trip-trop-tromp to where the grass is greener. It's an audience favorite at the Puppet Co., promising to keep the kids giggling. Three charming variety numbers precede the performance as an introduction to the Art of Puppetry.
