How to use: First, take out the 4 poseable character figures and 4 battle accessories from the set. Then, find the light - up Bat - Signal. Attach each character figure to the Bat - Signal and watch the figure's chest light up. Kids can then use the battle accessories and the characters to create their own Gotham City adventures. Note: Keep small parts away from children under 3 years old as they may be a choking hazard. Maintenance: Wipe the figures and accessories with a clean, dry cloth if they get dirty. Don't submerge the light - up Bat - Signal in water as it may damage the lights.
