Using these Goo Jit Zu DC Minis is super easy. Just grab a hero and stretch its body as far as you can - it can go up to 4 times its normal size. You can wrap them around each other to stage battles. When you let go, they'll quickly return to their original shape. For play, you can use them anywhere you like - on the floor, a table, or even outdoors. As for maintenance, keep them away from sharp objects to avoid tearing the goo out. If they get dirty, you can gently wipe them with a damp cloth. Don't expose them to extreme heat or cold as this might affect the goo inside. Have fun playing with your Goo Jit Zu heroes!
