Based on personal experience, I'd say this chap just swallowed a wererat magic user figure. If it was painted, there's a good chance he won't suffer anything adverse from the lead content. But passing it is no picnic. Again, personal experience. That was a horrible weekend.
This one... broke my heart. I can't and I won't say more than that, other than lead poisoning isn't the only risk you take when you surrender yourself to miniature fantasy figurines: you also risk your heart.
