if the head is glued on I would say factory error is possible
ya found a cute G2 baby oddball :-)
G2 heads turn! Adults do at least (aside from a select number of Magic Motion ones), I'm fairly certain babies do too, though I don't have any babies myself.I have a few G2 babies, and I can confirm that their heads do turn - this one's also does :)
Does the Christmas baby have that colour tail?
I would be happy to inspect things from the inside, but I've never taken a G2 baby's head off before*, and without knowing how the connector piece looks like, and how it connects the head to the body, I'd be worried to break her neck :( Does anyone have tips/a picture/a tutorial that would help with the process?
*nor any pony's thats head is connected to the body with a separate connector piece. I know this one has a separate piece, because as the head turns, in some positions the head and the body do not fit perfectly, and a white plastic piece is visible through the hole between them.
