Using the Trolls Hair Pops doll is super easy. First, look at the doll's plush hair and find the spots where the Hair Pops fit. Gently place the Hair Pops into the hair. When you want to reveal the surprise, just give the Hair Pops a little pinch and watch them pop out. The accessory inside can be used to store other small pieces, like extra fashions or shoes. As for maintenance, keep the doll away from sharp objects to avoid tearing the plush. If it gets dirty, you can use a soft, damp cloth to gently wipe it clean. Remember, this toy is for kids 3 years old and up, so make sure younger children don't play with it to prevent choking hazards.
