3D Explosive Potato for Unity, Shaders or Models? (Or both?) (+2 other potatoes!)

I am coding a mini-game for my app that will require the player to disarm an "explosive potato". The potato will have three wires that attach from the top down, and some will be crossed. The player will need to touch the CORRECT wire, or else they will be eliminated from the game. When the wire is touched, the wire will "break". If it is the correct wire, the potato's fuse will stop and the player will then be able to touch the potato freely. If a wire is cut, then a wire cut animation will be needed as if a wire was cut. If the potato explodes, a 2D animation will be played over the potato. If the potato doesn't explode, fuse will stop animating. SHADERS: The Edges of the wires should be highlighted in black, much like Borderlands art style, to make the wires stick out. The correct wire will be determined by shade - the wire with the most "different" shade should be cut. However, I will be the one scripting all of this out - I just need the core of the animations && ability to manipulate wires at will. I am not certain how this is best accomplished. Can dynamic wires easily be generated across the potato, or is a set list of static wires the way to go? Let me know. TWO OTHER POTATOES: Regular Potato, I will provide an example pic Fiery Potato: This potato will look like the regular potato, but it will also be ON FIRE! Edges of fire should have black outline, Borderlands style. The fire will be animated/added via Unity's particle system.
