We allegedly got the actual Bigfoot to make the sounds for our Emergency Bigfoot noisemaker. There were many long nights in tents with complicated recording equipment. At one point we even coated the microphone with peanut butter to get the sounds of him snorting! This 3-1/2" electronic Emergency Bigfoot noisemaker includes four sounds-howl, snort, roar and groan. You know, all the noises Bigfoot is known for. Batteries included.
