A resiliently deformable toy ball which is soft and supple and provides an intriguing relaxing feeling when squeezed, and which possesses a low rebound percentage due to its resliently deformable nature. The ball has a highly plasticized PVC core which is resiliently deformable due to its highly plasticized state. The PVC core is encased in a flexible polymer shell and both the core and the flexible shell are further encased in a stretchable fabric outer cover.
