Using your Heroes of Goo Jit Zu DC Goo Shifter action figure is easy! To start the fun, find the core (capsule) under Night Power Batman's chest and crush it. You'll see an amazing color change in his goo filling. You can also stretch the figure up to three times its size. It will always return to its original shape, so don't worry about over - stretching. When you're done playing, just put it in a safe place. Avoid exposing it to sharp objects as they could damage the stretchy material. If it gets dirty, you can gently wipe it with a soft, damp cloth. Remember, there are different characters to collect, each with a unique goo filling. Have a blast creating new adventures with your Goo Shifter heroes!
