How to use: First, take out the Barbie Marine Biologist doll from the package. Then, dress her up in the snorkel gear including the mask and fins. Use the lab equipment and marine life pieces to create an underwater scene. You can put all the pieces in the mobile lab when you're done playing. Open and close the lab case easily to store or take it on the go. Note: The doll can't stand by itself, so you may need to support it when posing. Also, be careful with the small pieces to avoid choking hazards. Maintenance: Keep the playset clean by wiping it with a damp cloth. Store it in a dry place to prevent damage. If there are any stickers, don't let them get wet to keep them sticky.
