Rerooting help- hard plastic toy

[nightmare.mal 10]

I’ve got one of those talking Celestia toys, I bought her for dirt cheap and she’s in very poor condition, I plan to use her for a custom. However unlike the smaller brushables, her entire body is made of hard plastic, and I’m not sure how I should go about removing her head. I worry a heat gun or boiling water would melt the plastic, but I’m not entirely sure as this is my first time working with such material. Attached is a photo of the toy in question.

Make her into Daybreaker. That would be cool!

Sorry, I have no idea. It's a kids toy so I know it's not made to come apart. Anyway, I'll look forward to seeing it.
