That sounds pretty cool.  I would give a listing of what powers she has as Snowbird.  Then the ones she has access too.  If it is shapeshifting - animals then what animals knowing some are easier to shift into than others.  Like snakes would be easy no real moving parts, cats, etc.  2/3 to start with the rest of the animal kingdom coming back as her memories progress or her powers start to return.  That is just my $0.02<br/>
