About this page

A mermaid rests on the seabed with a starfish tucked into her long wavy hair and her hands clasped in front of her, scaled tail curving out behind. Beside her stands a three tier cake, and instead of icing it is trimmed with branching coral and tube sponges on every layer. Three striped clownfish drift above, bubbles rise all around, and two starfish sit on the sand below.

This is the underwater page in our Happy Birthday coloring pages, the one that turns the whole party into a sea scene. The birthday camping scene and the birthday balloons over a city skyline take the same idea to dry land.

We rate this printable birthday coloring page as medium and good for ages 7 and up. Plan for about half an hour to an hour. The tail scales, coral branches, and fish stripes are all narrow, so colored pencils give the best control. Younger kids can color the tail in one shade and skip scale by scale.
