Caution: Proceed with Care!

A dark brown warning sign with yellow text and symbols. At the top, 'WARNING!' is displayed in bold, followed by a yellow triangular hazard symbol containing a stylized acorn. Below the triangle, the text reads 'WATCH OUT FOR ASSAULT ACORNS'. The sign is framed by yellow diagonal hazard stripes at the top and bottom. The design mimics official safety warnings but humorously applies them to acorns.
