The image features a cartoon illustration of a character named Lou Who, who is depicted as a pink, anthropomorphic fish. Lou is standing upright and is adorned with a pair of red antlers. Above Lou, there is a text that reads, "In a world full of Grinches, be a Cindy Lou Who." The text is written in a playful, handwritten font with a mix of red and green colors. The overall image seems to convey a positive and uplifting message, encouraging the viewer to be kind and cheerful, much like the character Lou Who from the Dr. Seuss book "How the Grinch Stole Christmas!"
