I think you could purchase them differently later on, or maybe now, but I remember getting the two big binders and getting all kinds of excited when the new stories (one page each) came in the mail.
They had four categories: Muppet Babies and The Muppet Show (which I designated in binder one) and Fraggle Rock and Kermit’s Stories which had cute little animal characters, including Bean Bunny who looked very unlike the Bean we know and love today. The Muppet Wiki doesn’t believe it to be the same character, and by characterization it doesn’t appear to be… but I didn’t know that when I was a kid.
I still love Bean. :D
