The image features a black and white illustration with a text that reads, "Jolly swear that I am up to no good." The text is written in a cursive font, and the words "Jolly swear" are emphasized by being larger than the rest of the text. The phrase "that I am" is also emphasized by being larger than the rest of the text. The word "up" is written in a larger font size than the word "to," which is in turn larger than the word "no." The word "good" is the largest in the text. The overall style of the image is reminiscent of a handwritten note, with the text and the footprints adding a playful and whimsical touch to the message.
