You can teach an Alien Bug some new tricks! The Yo Stick has a retractable string with a plastic ring on the end to attach it to your finger. The mechanism inside enables you to do tricks and have it easily come back to you! Inside the Yo Stick are two heavy-duty rubber bands that are adjustable and replaceable. You can adjust the tension to allow your Yo Stick to come back faster or slower. String is about 1.2m long when fully extended. The ends of the Yo Stick are rubber for safer play; this one features an out-of-this-world Alien Bug.
