The coolest $10 toy that makes a perfect cake topper or gift for littles. Comes with batteries, a screwdriver and the water bottle to fill the volcano. The water is a mist, not a steam so it doesn't burn. I used it for my Spooky Island Halloween party, but now it belongs to my three year old and he loves it for his dinosaurs LTKParties LTKHalloween LTKKids
