I'd love to see how you draw the cast of Extracurricular Activities. Harold Grifter is a personal favorite of mine, and being as busy as he is he might get pretty hungry~

A few ideas come to mind;
there's a Great Argon Lizard from Dragon Quest 8 lounging around on its back,
Girimekhala from the Megami Tensei franchise (the version everyone's used to from Persona 3 to 5 and SMT Nocturne) having eaten someone and slapping his belly in victory,
and a bara satyr dancing while playing on a pan flute to entertain somebody in his gut.
