The present invention relates to a toy including a carriage (12), a pair of wheels (14), a sliding part (16) mobile along the carriage between extended and retracted positions, a spring stressed between the carriage and the sliding part, and means adapted to i) to progressively store a mechanical energy in the spring by displacement of the sliding part towards the retracted position, and ii) to release the thus-stored energy. The sliding part includes an end (32) supporting a jaw (34) and a pad (36). The carriage includes a protruding part (24) supporting another jaw (28) and another pad (30). The carriage may be oriented relative to the ground between several functionally distinct stable positions, with a default position where the toy rests in stable equilibrium on the two wheels and the pad (36), and a pulling/grasping position where the toy rests in stable equilibrium on the two wheels and the other pad (30) and where the second jaws is movable parallel to the ground, further or closer to the first jaw.
