Babushka Dolls

Bumble 🐝
I recently inherited a collection of babushka dolls. I remember fondly of playing with them at my grandmothers house as a little girl but I was still really young when my father had a falling out with my grandparents. I vaguely remember there being a song you sing while playing with them and it feels like it's at the tip of my tongue but it's not coming to me. 
Does anyone know what I'm talking about? I'd love to be able to pass it on to my own children now that I'm grown since it's one of the only memories I have of my grandparents and I don't have anyone else to ask.
