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).  

Balloon Blowing Monkey (shown on right) 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.  Unfortunately Monkey while still working can no longer can blow up a balloon, most likely due to the rubber air hose drying out and breaking into pieces (a common issue with these toys as well as the bubble blowing toys and smoking toys as they all used a similar rubber tubing.
