How to play: You can stretch the figures up to 3 times their size, which is up to 25 inches (60cm), and watch them return to their original shape. To use the 'Pop Out' attack, simply squeeze the figure's arm. The figures are great for kids' hands - on play, with their stretchy and squishy parts. Notice: Keep these figures away from sharp objects as they may damage the goo filling. Avoid excessive pulling that might tear the figure. Maintenance: If the figures get dirty, you can gently wipe them with a damp cloth. Store them in a cool, dry place to keep the goo in good condition.
