Using the Schleich® Adventure Tree House is easy and fun. You can place the human figurines and animals anywhere in the tree house. Let the kids use their imagination to create different scenarios, like picnics or animal - watching. When using the pulley to lift the puppy, make sure to do it gently to avoid any damage. As for the little bird and hedgehog, you can position them in their special spots. When it comes to maintenance, keep the set away from sharp objects that could scratch the figurines. If it gets dirty, you can use a soft, dry cloth to clean it. Don't submerge the set in water as it might damage the paint. Store the set in a dry place when not in use to keep it in good condition.
