The MEGA Barbie Color Reveal building sets hide fun surprises. The appearance of each little doll is a mystery waiting to be revealed. Start by opening the heart-shaped container and finding the 2 surprise bags. Inside, you will find 10 surprises, including a small Color Reveal doll. Fill the container with warm water, place the doll inside, and spin it to reveal its appearance. Then, dip the sponge in icy water to transform its appearance. Place the remaining items in warm water and uncover more surprises. Build the boat with the Color Reveal base to discover fish and place both little dolls inside to start exploring. Then, build the rings to learn tricks with the dolphins. When it's time to relax, build the beach hut and have fun in the sun.
