Using this daddy shark costume is super easy. Just put on the jumpsuit. Once you're all set, you can turn on the sound chip by flipping the on - off switch to enjoy the baby shark song. When you're done, turn it off to save battery. As for care, gently hand - wash the jumpsuit in cold water with mild detergent. Don't wring it out too hard to avoid damaging the plush material. Hang it to dry. Keep the sound chip away from water as it can get damaged. When not in use, store the costume in a cool, dry place to keep it in good condition.
