The image features a cartoon illustration of a purple shark with a cheerful expression. The shark is wearing a festive Santa hat, which is red and green, and has a red bow on top. The shark's eyes are large and black, and it has a wide, toothy smile. In the background, there are small snowflakes and a faint outline of a Christmas tree, suggesting a holiday theme. At the top of the image, there is text that reads "Cousin Shark" in a playful, hand-drawn font. Below the shark, there is additional text that says "Doo Doo Doo Doo Doo" in a similar style, which is likely a reference to the "Doo Doo Doo Doo Doo" song from the "Finding Nemo" movie. The overall style of the image is whimsical and child-friendly, with a clear focus on the shark character.
