They are obviously Miss Piggy...
...Kermit, and Fozzie.
What you may not notice is that they are meant to be the Muppet Babies versions. "Muppet Babies" was a popular animated series at the time,airing originally from 1984 to 1991. There were a lot of dolls, toys and other products released from it. Emma was born in 1991, and I bought plenty of Muppet babies toys and stuff for her. Her first calendar, which I kept track of her baby milestones on, was a Muppet Babies one.
They're McDonald's toys.
Kermit and Fozzie are about 7 1/2" tall, but Piggy is about 8 1/2".
You can see two different commercials for the toys HERE and HERE.
Tomorrow we'll see that wintery doll.
