Tinker is a Regular pegasus who runs Tinkers Hardware and Repair in Ponyville. She does this by using her special talent to be able to visualize and calculate almost anything in a Mechanical Sense. She lives on the second floor of the shop and does repairs and contract work for a living. On occasion, a pony comes to her with an idea for a machine and she can make it happen. Now imagine how Tinker's life is affected when Nightmare Moon comes knocking from the moon after so long. Well, she doesn't sit at home that's for sure. Come along with our Mechanically Inclined mare as she grumbles along with "Saving the world" or whatever.
