Do some 3D Modelling of an electronic potato game

We are designing an electronic game in the form of a potato. The potato needs to be approx. 3 inches in diameter and 6 inches in length. Needs some sort of silly face. Potato is to be brown in color and there will need to be a multi layer to the potato. On the opposite side of the potato from where the face is shown, needs to be the word "Shocktato" in block letters in a font that is shocking. The inner layer will be brown like a potato and the thin outer layer will be made of a shock absorbent clear rubber to withstand falls if dropped. There will be little metal nubs (9mm in diameter) around the potato that will be electric conductive to provide low voltage shocks to the players. On the nubs there needs to be the small design of a lightning bolt. on the right end of the potato there needs to be two small switches. 1. On/Off switch. 2. Shock Strength Switch. (1,2, and 3). See attached image for basic look.
