Ok so to pair them up in sets
The castle had...
Kermit(2) (1)King Outfit (2) dressed as a Knight
Gonzo (1) dressed as a knight
Piggy (1) Regular Clothing
Bunsen = Wizard Outfit
Beaker = Jester Outfit
The fun fair/Train set had...
Kermit = Regular Clothing
Piggy = Regular Clothing: Exactly like the first one, the same thing
Gonzo =Regular Clothing
Fozzie = Regular Clothing
Scooter = Regular Clothing
Skeeter = Regular Clothing
Animal = Regular Clothing
Rowlf = Regular Clothing
So the Castle had 6 Muppet figures where as the Train had 8, but to even it out the Castle came with a Dragon and a Horse.
I wish I had the Train instead, but I had a Disney train which was the same but yet not Muppets.
