A toy or novelty is disclosed which is in the form of standing mobile and has a series of parts each pivoted to another and each provided with eccentric weights. The weights and the arrangement of the pivots may be operative to pivot the parts from a position aligned with each other to a position extending from each other when the stability of the parts is sufficiently disturbed from the condition of stability when such parts are filed or folded. Alternatively, the parts may simply rock in an undulating fashion from the extended condition of stability. Some of the parts may have printed matter thereon which make sense or nonsense in one condition of stability or make sense or more sense in the other condition of stability. Some of the parts may include two parallel walls substantially to enclose other of said parts in the filed position. The parts may be circular in form and of reduced diameter in ascending order in one condition of stability. The weights of each part preferably decrease in mass from one part to the next and the two conditions of stability are when the centroid of the weights and pivots are aligned.
