Things that come in a chip form
The first two clues, Chocolate and Potato, strongly suggest common snack foods: chocolate chips and potato chips. This is a very tempting connection. However, the theme breaks on Wood, Poker, and Computer. While 'wood chip' is a perfect fit, the term 'poker chip' or 'computer chip' doesn't describe a 'form' in the same edible sense, making the logic inconsistent for all five clues.
