I can't really fathom her carrying around a decidedly non-kosher toy animal [...] and calling it "Rabbi".

Connie, hon, human isn't a kosher animal either, yet I'm pretty sure I've heard of a rabbi or two who was that species. Heck, legend has it Hillel was an H. sapiens.

May I suggest now would be a great time to introduce the children's book The Rabbi and the Twenty-Nine Witches?
