This toy emplys a large drill to dig tunnels into a snowbank. Using an electric current to heat the drill, as well as propel the motor running it and the 28 wheels on the body allow it to move through snow with relative ease. A long sturdy power cable doubles as a pull cord to get it back out.
The physics of the screw is the major player in this toy, and is the cause it can move through the snow. Made out of a pastic, the construction process would have to ensure a water-tight seal at every component in order not to short circuit and possibly injure the user.
This toy is meant for children 6 years of age and older.
