Here's some designs I did on Miss Tiny.
Design 1: Same shape body and color, but same bow tie like Miss Naughty, but dark blue. Same nose like Miss Helpful, but dark pink.
Design 2: Same body shape, but orange like Mr. Small. Similar hairstyle like Miss Calamity and Miss Daredevil. Similar top hat hat like Mr. Small, but yellow with a white stripe. Same shoes like Miss Magic, but red.
To me, I won't mind what Miss Tiny looks like in the show, as long she's still small, I'll still love no matter what.
