This design features a playful and colorful character, a purple shark, with a big smile and wearing black glasses. The shark is holding a yellow pencil, adding a touch of whimsy to the image. Above the shark, the word "Teacher" is written in bold blue letters, while the word "SHARK" is displayed prominently below, also in blue but with a pink outline. The phrase "Doo Doo Doo" is repeated three times in pink, playful font, creating a fun and engaging visual effect. The overall design is lighthearted and cheerful, likely intended to bring a smile to anyone who sees it.
