This design features a square graphic with a black background. At the center, there is a text that reads "I Solemnly Swear That I Am Up To No Good" in a playful, stylized font. The text is colorful, with the words "I Solemnly Swear" in white, "That I Am Up To" in pink, and "No Good" in blue. Below the text, there is a row of footprints in white, suggesting movement or travel. The overall style of the image is reminiscent of a comic or a cartoon, with a casual and fun tone.
