Flandre model over Pit?

[TokoyamiTheDark]

Hi, I was wondering how I could rig Flandre's model over Pit, as ever since it has been shown it was possible, I was wishing to do it...but I don't know how, or at least, I don't know how to prevent the model from deforming when bones are rigged. Can anyone help?

Guess who's already doing a Flandre on Pit. :srs:
I'll give you a hint. Starts with R and rhymes with you.

Of course, if this is just to further your knowledge, please proceed. :D
