Jack Skellington's faithful ghost dog Zero lights the way! His nose glows with an LED light that's activated with contact. Each Zero Scentsy Buddy comes with a Scent Pak in our The Nightmare Before Christmas: Jack's Obsession fragrance. 10" tall Please note: There is no replacement battery for the light-up nose on our Zero Scentsy Buddy. His nose lights up on contact and remains lit for about five seconds each time. The lifetime of the battery is approximately three hours in a working state — which breaks down to approximately 2,160 taps. This may vary from Buddy to Buddy. When the light eventually stops working, it is not a defect eligible for replacement.
