This design features a playful and colorful illustration with a central theme of marine life. At the top, the word "SISTER" is written in large, bold letters, suggesting a connection to a female sibling. Below this, the word "SHARK" is prominently displayed, indicating the presence of a shark character. The shark is depicted with a friendly expression, wearing a pink bow on its head, and is surrounded by various sea creatures and objects. These include a yellow fish, a pink and purple fish, a green seaweed, and a blue bubble. The background is a light blue color, which could be interpreted as water. The overall style of the image is cartoonish and child-friendly, with a focus on bright colors and simple shapes. The text "DOO DOO DOO" is also present, which might be a reference to the sound a shark makes.
