"Create an illustration in flat colors of Bigfoot standing in a dense forest, surrounded by tall trees and lush greenery. Bigfoot should be depicted as a side-view silhouette with a proud and confident posture, as if celebrating a victory. Above or below the Bigfoot silhouette, include the text 'World Hide and Seek Champion' in a bold, eye-catching font. The overall scene should have a mysterious and mythical atmosphere, with the use of simple, flat colors to enhance the legendary status of Bigfoot."
