A throw and fetch system includes a universal handle, at least two projectiles, and at least two interchangeable projectile holder elements. A first projectile has a first size and/or shape, and a second projectile has a second size and/or shape. A first interchangeable projectile holder element has an interior that is sized and shaped to correspond to the size and shape of the first projectile, and a second interchangeable projectile holder element has an interior that is sized and shaped to correspond to the size and shape of the second projectile. In a first state the first projectile holder element is attached to a distal end of the universal handle such that the first projectile may be held then thrown therefrom by a user, and in a second state the second projectile holder element is attached such that the second projectile may be held then thrown therefrom by the user.
