A Snoopy Snow Cone Maker
I know, they’re the CLASSIC toy and you probably always wanted one and your parents probably refused to buy it. The thing is, turning a manual crank to shave ice is fun for maybe thirty seconds, tops, and you need to crank for a good fifteen minutes to shave enough for a snowcone. Also, the handle will probably break off after five.
You can buy a full-on electric ice shaver for $10 more than the Snoopy one. Drop in ice cubes, close the lid, and turn it on. Because what your kids want is not actually the opportunity to manually crank an ice shaver with Snoopy on it; what they want is the ability to make snow cones at home.
