The Miller's Daughter
From Muppet Wiki
The Miller's Daughter appeared in a Sesame Street News Flash sketch in the mid-70s. In the sketch, Rumplestiltskin appears to the Miller's Daughter and threatens to take her baby if she can't guess his name. She can't, so he grabs the baby carriage -- with Kermit inside.
Miss Piggy plays a different version of the Miller's Daughter in Muppet Classic Theater.
