INCLUDES 1 RANDOM COLORS - This caterpillar is a super cool fidget! The bug is quite large measuring in at 7" long and 2" wide. The caterpillar is made up of several hard plastic bowls that are connected. This gives the slug a jointed and robotic movement. You can twist and spin the slug in your hand. The hard plastic makes a nice sooting sound as the colored cups rub together and move. It is quite mesmerizing to feel. Great sensory toy.
