How can I use Chocos the Monkey's Tail on Human figures?

Cyrinadia

Hello All,

As per title.Trick is, the tail bones don't follow dialling out Chocos. Like, as Chocos "evolves", the tail 'bones' get left behind and lay well below the tail.

I tried adjust rigging to figure, that doesn't do it. I tried Transfer Rigging Figure Space, and that doesn't work. Any ideas? Seems the tail only has the Hip and Pelvis bones. Should I manually set the bones? And would I then ERC freeze them? Would that mean that any time I change the base figure shape, I'd have to also redo the bones? I mostly got Chocos coz he's cute and also to use the tail.

Please halp?
