How to use: First, take out all the construction pieces and start building your playground for the Nano Bugs. Connect the flexible walls and connectors to create different shapes. Then, place the 2 Flash Nano Bugs and 2 Nano Bug 3 Merry Go Rounds into the playground. Watch as they start exploring on their own. Note: This toy is for kids aged 3 and up. Keep small parts away from younger children to avoid choking hazards. Maintenance: If the Nano Bugs stop working, check the batteries. You can use a dry cloth to clean the toys if they get dirty. Have fun playing with your HEXBUG Nano Flash Nanoplex Set!
