Stockwell is the keeper of a shop in Hyrule town in The Minish Cap. He lives by Lake Hylia, with his pet dog Fifi. There is a section above Stockwell's shop that you can enter if you are tiny to get behind the counter, where at a certain point in the game, a bottle appears. If Link takes this bottle of dog food to his house and feeds Fifi, he gets to keep the bottle. Fifi claims, though, that it wishes it master would visit more often and play with it.
