This soothing mushroom shaped sensory ball is so cool it is like magic. The ball is filled with a thick doh like material inside its flexible skin. The skin has a soft mesh webbing looking like spots on the mushroom, and when you squeeze the ball the interior blob pops through the mesh and expose the inner ball. 3 color options - Pink and Yellow / Blue and Pink / Orange and Purple. The ball is about 2.5". This is very calming because it has a very silky soft feel, and it is filled with a thick soft almost fluffy doh that looks like soft serve ice cream. You need to feel it to really know how nice these are.
