Like our large self inflate whoopee cushions, but this one you can carry around with you on your key chain. Just squeeze and it will make a small farting sound that will make you giggle with laughter. Can be used manually by just squeezing or place this on a small chair like for a small person and it will make a farting sound to startle them just like our large ones. Variety of colors, color choice not available but all look great. Fun gift for stockings, holidays, birthday and party favors.
