To use these Minecraft Pig Fusion Figures, simply take the parts and snap them together. It's easy and doesn't require any tools. You can build a single figure or swap body parts with other figures (which you need to buy separately) to make your own unique hybrid characters. When playing, be gentle with the parts so they don't break. Keep them away from small children who might put the parts in their mouths as they could be a choking hazard. To maintain the figures, you can use a dry cloth to wipe off any dust. Don't expose them to extreme heat or moisture as it might damage the colors or the plastic.
