A toy grabbing mechanism for catching or gripping a toy includes a main body, claw members, and a movable member. The main body has holes. The claw members each have a gripping portion, a pivoting portion and a balancing portion. A balancing portion is provided at one end of the claw members penetrating through the elliptical holes respectively. A gripping space is defined between the gripping portions of the claw members. The pivoting portions are pivotally connected to the movable member and surround the main body. During operation, when the three claw members are in contact with a surface of the toy and the toy exerts pressure on all of the three claw members, the three claw members are extended in a way such that a volume of the gripping space is increased to completely encompass the surface of the toy.
