This design features a cartoon depiction of a shark with a festive twist. The shark, which is pink, is adorned with a Santa hat and a red bow, giving it a holiday-themed appearance. The shark's mouth is wide open, revealing its teeth, and it has a big smile on its face, adding a cheerful touch to the image. Above the shark, there is text that reads "Sister Shark," suggesting a playful or affectionate relationship between the shark and another entity, possibly a sibling or a friend. Below the shark, there is additional text that says "Doo Doo Doo," which could be a reference to a popular children's song. The background of the image is white, which contrasts with the vibrant colors of the shark and the text, making them stand out. The overall style of the image is simple and cartoonish, with a clear focus on the shark and the holiday-themed elements.
