I'm writing this for one reason and one reason only.
If I have to read another post about Moria inserting Robin's shadow into Odz and having his arms sprout all over, or any other DF being transfered I'm going to be upset.
Moria cannot make Odz a Rubber-Man.
Moria can make Odz stretch by stretching Odz's shadow. Technically Moria could make any (single) zombie stretch. This is just an odd fit of serendipity, or perhaps genius, that Luffy can stretch and so can Odz. If anyone else's shadow was in Odz he could still stretch but of course he wouldn't be used to it.
For all of those who understood that already you don't have to say anything.
