Simply pull the key chain pin and roll it by your next victim, the FART NINJA Grenade will do the rest! Once it stops moving youll hear one of 10 realistic fart sounds. If you choose to use as a key chain you can also activate the sounds by holding down on the sensor for 1 second. FART NINJAS Grenades Series 1 is a collection of 4 different collectible grenades modeled after your favorite Fart Ninja figures.
