What does Bigfoot sound like? They 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 they even coated the microphone with peanut butter to get the sounds of him snorting! But, that hard work paid off and now you can use this simple device to have Sasquatch sounds whenever you need them. Which is probably about once every 20 minutes, right? 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. Three LR44 batteries included.
