A toy doll may include a body supported by a skeletal structure including one or more joint assemblies. A joint assembly may include a pivot block further including a pivot stop, and a joint member rotatably coupled to the pivot block, the joint member further including a stop protrusion configured to engage the pivot stop upon rotation of the joint member in a predetermined direction, wherein engagement of the pivot stop prevents further rotation of the joint member in a predetermined direction, wherein the joint member is moveable through a predetermined range of motion transverse to the plane of rotation of the joint member, and wherein movement of the joint member transverse to the plane of rotation allows the stop protrusion to bypass the pivot stop.
