To use this ZURU Smashers Nano Jurassic Light - Up Dino Egg, first, unwrap the egg. Then, smash it open to start your adventure. You'll find glow - in - the - dark slime inside. Dig through the slime to find the dino parts. Once you've found all the parts, build your nano SMASH - O - SAUR. Remember, there are over five surprises like slime, dino parts, and glow - in - the - dark stickers. There are six different dino characters to collect, so keep smashing and collecting! This toy is suitable for ages 3 and up. For maintenance, keep the toy away from sharp objects to avoid damage to the slime or dino parts. If the glow - in - the - dark feature seems to fade, expose the toy to bright light for a while to recharge it. Also, after playing, make sure to clean your hands as the slime might be sticky.
