Using this Heroes of Goo Jit Zu Versus Pack is easy and super fun. First, take the figures out of the box. You can start the battle right away! For Spider - Man, just squeeze his body to feel the squishy gel beads inside and watch the goo move. With the Goo Shifter Lizard, find the Core under its chest and crush it. You'll see a color flow within its body, powering it up. When playing, you can stretch both figures up to 3 times their size, and they'll return to normal. As for maintenance, keep them away from sharp objects to avoid tearing. If they get dirty, you can gently wipe them with a damp cloth. Don't leave them in direct sunlight for a long time, as it might affect the goo inside. Have a great time playing with your Marvel heroes!
