Help, trying to figure out a child's game! Sneak behind The Fox?

[Tinkjon]

DD has come home from Year 1, raving about a game called Sneak Behind The Fox. She wants to play it at home but I can't understand what she's saying at all! Someone sits in the middle of a circle and closes his eyes, then someone else creeps up and whispers to them. Then people wink or blink and say "Mr Fox, your child has gone" and you have to work out who whispered.... or something like that - the details are very sketchy!

Google brings up nothing - does this ring a bell with anybody?

Try googling Grandmothers Footsteps.

Or What's The Time, Mr Wolf.

Thanks for the suggestions but it's none of those two I think they're both just sneaking upon people, but this one involves whispering and trying to guess who's voice it was.
