You know when you see something and its the most adorable thing ever but you have no idea what it is and regardless you HAVE TO buy it? Well that was us with this adorable sea urchin! not only is it adorable it is suuuper entertaining! Its a squishy and has many soft spiky balls all around it and it hands from this cool slinky string so you can watch it bounce up and down and up and down....honestly its the weirdest, cutest, most awesome fidget! We love it!
