How to use: First, put the 5 colorful balls, including the character ball, into the truck. Then roll the truck on a flat surface, and the balls will be launched out. After that, collect the balls and repeat the process. Notice: Make sure to use the toy on a clean and flat surface to avoid any damage to the truck or the balls. Keep small parts away from children under 3 years old to prevent choking hazards. Maintenance: If the truck gets dirty, you can use a damp cloth to wipe it clean. Store the balls and the truck in a dry place when not in use.
