I think last time they localized this as microphone for dolls. Which is what the Japanese term was. 人形用マイク。I guess VIZ thought it was a bit odd since this wasn't really a doll, but I think that's a silly decision.

And yes, Girl's Festival is Hinamatsuri which we had a chapter about. Also, aw, the term translated to baby doll is 抱き人形 which means "hugging doll".
