Even the Halloween-themed mechanical toys are remote controlled these days. Take for example this, an 8 inch tall remote controlled zombie with posable arms and head. The remote is shaped as...you guessed it: a brain. When you activate the remote, the Zombie plods forward and groans.
This undead fellow would be a great (if unwelcome) guest at a Barbie Picnic or Hanna Montana concert. Or, give him a walk-on part in High School Musical -- just no lines.
