[Legs From Here to Homeworld spoilers]
There's an established theory that the diamonds' ships can merge together into one ship, or somehow make up one body.
We know that Blue and Yellow have arm ships. Pink's ship was revealed to be two legs and a butt. The shoes do not match Pinks and instead more resemble White's heels. On Homeworld, the shape of White's head and probably part of the upper body are always visible, and it is apparently the structure in which White Diamond resides. So, theoretically, we have seen the entire body ship, and it roughly resembles White Diamond, with her hair and shoes. It would have pink legs, one blue arm and one yellow arm, with a torso and head belonging to White.
So if we have completed the ship, this begs the question: where does the green hand ship fit in? Are there other body ships in Green or other colors?
