Using the Creatto Puppy Pals set is a breeze. First, take out the 150 Creatto pieces and start connecting the plastic tiles according to your design to build the puppy shapes. The tiles interlock easily, so you can quickly assemble your cute puppies. Then, attach the string of 30 LED lights to add a special touch. Remember, the lights need 2 AA batteries, which you'll need to buy separately. When you're done playing, store the pieces in a dry place to keep them in good condition. If the tiles get dirty, you can wash them with mild soap and water. This set is great for kids aged 8 and up, so have fun creating your puppy pals!
