Ah ok, thought it was possible already since the picture above shows her with way more muscles. Can you grow any girls beside Mia atm?
Huh now I'm a bit confused since I thought from your previous answer that you can't grow Rachel in the current version (I was playing ver. 1.6). Do you mean that Ava, Rachel and Emily will be growable in the public version in future updates and the rest will only be growable in the paid version in future updates?
