Using the Peppa Pig Themed Aquadoodle Activity Bag is super easy. First, fill the Aquadoodle pen with regular tap water from your faucet. Then, gently run the pen's nib over the magic mat, and you'll see colours pop up right away, just like magic! This is a great way to keep your kids busy during trips or at home. When using it, make sure the pen is filled properly but not overfilled to avoid leaks. Also, don't press too hard on the mat. After you're done playing, let the mat dry naturally. There's no need to clean it with any special products because the water just dries up, leaving no mess or stains. Store the bag in a cool, dry place to keep it in good condition for your next play session.
