Here we have an awesome example of creativity generously slathered on battery operated toys in the 1950s.  Looking for new and exciting actions ALPS came up with the idea of a toy capable of blowing up a balloon.   Amazing that a small battery powered air pump mechanism put our enough pressure to actually blow up a ballon (pre-stretching the balloon helps increase maximum size).  

Teddy Balloon Blowing Bear (shown on left) also features an internal air pump that really blows up a balloon attached to his hand (air nozzle).  Actions also include Lighted eyes with voice, hands raise/lower, and his feet stomp.  This Teddy is fully working although his "lungs" are not as strong as they used to be.
