Create an illustration featuring a stylized, menacing puppet with a featureless mask. The puppet should wear a dark, tattered jacket and have a sinister grin. Include a playful, cartoonish cat beside it, with exaggerated features like big eyes and a wide smile. Instead of the number "13," use a dripping "07" in bold, graffiti-style lettering. Set the background to a spooky gradient of dark green and black to enhance the eerie atmosphere.
