How to use: To activate the blue color transformation of Blue Strike Spider - Man, simply crush the core (capsule) under his chest. You can also stretch him up to three times his size and watch his squishy body move. Squeeze him to feel the unique goo filling inside. Collect all 4 heroes to enjoy different 'Goo - formations'. Attention: Keep small parts like the core away from children under 3 to avoid choking hazards. Don't stretch the figure too forcefully as it may damage the material. Maintenance: Store the figures in a cool, dry place to prevent the goo from drying out or getting damaged. If the figure gets dirty, you can gently wipe it with a soft, damp cloth.
