Humm, Ssmoke usage make for speedy feeders. I think if I could play around all day with Ssmoke, and have that much fun as a kid, who would be fat, but maybe the actual usage of Ssmoke uses some of the calories up, I have heard that thinking does burn calories. And the kids need to think a little bit about the Ssmoke, sure some things become automated like breathing, but, maybe it helps them stay fit.
