This little thing is so cute!!! The air from the diffuser shoots out of her mouth. All you do is fill a little bit of water until you reach the water line and add 1-3 drops of your favorite essential oil. There’s a little button you press on the side to turn it on, just press it a few times and wait for it to start coming out. It must be plugged into an outlet. I’ve used this a couple of times but I’m not a fan of essential oils too much so I’m looking to get rid of it.
