Like-new Senger Dolphin! The dolphin can be heated or cooled, giving your child the perfect amount of warmth or coolness they need. To warm, please remove the cherry or grape seed pouch. Simply open the zipper at the bottom of the animal's belly. Microwave the pouch on low for 20 seconds, and if needed, microwave in additional 10 second increments at a time, ensuring that it is not too hot to the touch.
