The MEGA Barbie Color Reveal construction sets hide fun surprises. The appearance of each small 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 swirl it around to reveal its appearance. Then, dip the sponge in cold water to transform its look. Place the other items in warm water to reveal more surprises. Build the boat with the Color Reveal base to discover fish and place both small dolls inside to start the exploration. Next, build the rings to teach tricks to the dolphins. When it's time to relax, build the beach hut and have fun in the sun.
