At the center of the page, you will find the friendly hippopotamus with its round belly and cute snout. Notice the small bubbles rising from its nose, creating a sense of movement in the water. The background features various aquatic plants that sway back and forth as the water moves around them. These plants add a sense of life and texture to the underwater environment.

Look closely at the seabed where the plants take root. You can see the texture of the ground and the way the bubbles float toward the top of the page. Each element, from the hippo's tiny ears to the broad leaves of the underwater greenery, provides a unique space to fill with your favorite shades. The composition is balanced and peaceful, making every detail easy to see and color.

While many people think of these animals as gray, you can use soft purples or even light blues to give your hippopotamus a more magical, cartoon feel. Try using a darker shade of your chosen color for the underside of the belly to show how light filters through the water from above. This simple shading trick adds depth and makes the character look more three-dimensional.

For the aquatic plants, mixing different greens like emerald and lime will help them stand out against the blue background. You might even leave some of the bubbles mostly white with just a tiny hint of light blue or silver around the edges to make them look like they are shimmering. Experiment with light pressure for the water to keep the background looking soft and fluid.
