An apparatus is provided, which includes a plurality of elongated strands having joinder regions uniting adjacent strands at a distance along a length of an outer perimeter of the elongated strands, the elongate strands being configured to couple together for a distance along their lengths. The elongated strands form a surface of a mesh when the joinder regions are coupled. The apparatus may further include a manducable protrusion coupled to the mesh and extending a distance away from an exterior surface of the mesh.
