You will find a large shark in the center holding a detailed treasure map featuring islands and a compass rose. An open treasure chest sits right in front of him, overflowing with gold coins, pearl necklaces, and sparkling jewels. Look closely to see the small octopus wearing a bandana and a tiny crab sitting on a nearby rock.

The background is filled with swaying seaweed, scattered rocks, and rising bubbles that make the underwater setting feel alive. Every element, from the individual coins to the textures on the rocks, offers a fun area to add color. The shark's pirate hat and the octopus's bandana add a fun personality to these ocean dwellers.

For the shark, try using shades of blue or gray, but a colorful pirate hat like deep red or purple adds a great touch. The treasure chest looks best with warm browns and bright yellow for the gold coins inside. You can use different colors for each jewel, like emerald green or ruby red, to make the treasure really pop against the ocean floor.

Use light blue or teal for the water around the characters, and keep the bubbles a very pale blue or even a light lavender to show they are translucent. The treasure map can look like old parchment if you use a light tan or beige color. Adding a bit of darker green to the seaweed will help it stand out against the blue water.
