You’re probably wondering how we got the actual Bigfoot to make sounds for our Emergency Bigfoot noisemaker. Let’s just say we bribed him with pizza and an IPA. This 3½" (8.9 cm) electronic Emergency Bigfoot noisemaker includes four sounds—howl, snort, roar and groan. You know, all the noises Bigfoot is known for. Plastic. Three LR44 batteries included. Illustrated card sleeve.
