The "Finding Nemo" live stage show uses the new style of puppets.
For all the main characters, a person (or several people -- with turtle above) carries the puppet, and is in plain sight.
Other puppets appear as well: fanciful sea creatures float across the stage or into the audience; held aloft on long poles, they billow and undulate in a way that totally suits the underseas.
People who've seen Disney's Broadway show, "The Lion King", will recognize the style: the puppets in "Finding Nemo" were designed by Michael Curry, who co-designed the character puppets in The Lion King.
By the way, the puppet Crush, above -- the cool sea turtle dude-- is a big guy, nearly the size of a Volkswagon.
