In the center of the page, a large octopus with big, expressive eyes and a wide grin takes center stage. Its wavy tentacles curve around, making it look like it is dancing through the water. Right next to the octopus, you will spot a striped lollipop that looks like it drifted down from a candy shop. Floating just above the tentacles are a five-pointed star and a small heart, adding a whimsical feel to the underwater world.

Tall blades of seaweed grow from the bottom of the frame, providing a natural habitat for our eight-armed friend. Tiny bubbles of different sizes rise toward the surface, filling the empty spaces with circular patterns. Every element, from the octopus's suction cups to the stripes on the candy, offers a new detail to focus on as you work through the scene.

Since this is a cartoon scene, you can use any colors that make you feel happy. For the octopus, bright shades like purple, orange, or teal would look fantastic. You might even want to use a different color for the underside of the tentacles to make them pop. The lollipop is a great chance to use contrasting colors like pink and yellow or blue and orange to make the stripes stand out.

To give the water a sense of depth, try using a light blue or seafoam green for the background. You can leave the bubbles white or give them a very light tint of iridescent lavender or silver. The seaweed looks great in various shades of green, perhaps with some darker outlines to show the texture of the leaves. Using glitter pens on the star and heart can make them look extra special.
