This lobster is a super cool fidget! The crustacean is quite large measuring in at 9.5" long and 2" wide. The sea critter is made up of several hard plastic bowls that are connected. This gives the animal a jointed and robotic movement. You can twist and spin the gator in your hand. The hard plastic makes a nice soothing sound as the colored cups rub together and move. It is quite mesmerizing to feel. Great sensory toy.
