The Martian "Guided Whistle" Bloon-Rocket with Jet-Blast Bloon-Gun is one of the most wonderful toy space guns ever made. Breathtakingly beautiful, it is fitted with a balloon which is blown up by blowing into the end of the barrel. According to the information on the card which accompanies the gun, the balloon "blasts off for the moon" when the trigger is pulled. Length 9 1/2 inches.
