"Saw" Billy the Puppet     
Billy was made from a 12" puppet figure and tricycle combo produced by Neca.  I took parts from
both,  then scratch-built the rest.  Everything remains connected during transformation, no
"parts-forming.  I took the sound chip from Billy and installed it in the custom base, which quotes
six lines straight from the movie at the push of a button
