At the center of the page, the mermaid has a wide, happy smile and flowing hair that looks like it is waving in the current. She is reaching out toward a group of sea turtles, who seem to be swimming alongside her on a grand journey. Each turtle has a distinct shell pattern that you can decorate with different designs.

Small fish dart around the edges of the page, adding movement to the water. At the bottom, detailed coral formations grow in various shapes, offering plenty of tiny spaces to fill with bright colors. Throughout the water, round bubbles of different sizes rise toward the surface, completing this cheerful underwater landscape.

To make the mermaid's tail stand out, try using a shimmering metallic gel pen or a bright gradient of greens and blues. For the sea turtles, you might use different shades of olive, brown, and tan on their shells to give them a natural look. The coral reef is the perfect place to use your most vibrant crayons, like neon pink, bright orange, and sunshine yellow.

Since there are many small bubbles and fish, using fine-tipped markers can help you stay within the lines for those tiny details. If you want to create a sense of depth, try coloring the water at the bottom of the page a darker shade of blue and gradually making it lighter as you move toward the top where the sun might be shining through.
