Using your Armored Energy War Machine is easy and fun! First, to transform the hero, find the core (capsule) under his chest and crush it. You'll see an amazing color change in the goo filling his body. You can also squeeze and stretch him as much as you like - he can stretch up to three times his size and will always return to his original shape. When playing, make sure to handle him gently to avoid damaging the core or the stretchy material. After playtime, just store him in a cool, dry place. Don't expose him to extreme heat or sharp objects, as this could affect his squishy texture and durability. Have a blast collecting and playing with all the Heroes of Goo Jit Zu Marvel Goo Shifters!
