I'd like to throw in Humpty-Dumpty, Rapunzel (With a longer hair piece) and pinocchio.
Humpty-dumpty might be a long shot as it would require a large 'over-body' mould (like the minotaur) and I know their might be issues with infringing on disney areas. But something like 'Tower Princess' with a long braid, and 'boy puppet' with short legs and a long nose would create great new parts.
(I had also thought of female mermaid, medusa, female elf, cyclops and prince charming but they were already on the list!).
How about a cupid type figure? Short legs, bow and wings?
Less talking, more MOCing.
