Thanks for the assist, Drtooth. The reason why I asked about Cookie Hood's horse is because Robin Hood's lady love's name was Maid "Marian" so this hopefully clears up the confusion. Now, if you could, please answer the other two questions I asked.
Somethingofafan, or should it be SomethingOfAFan?
Super Grover, is in my mind at least, sufficient cause to be listed as a different character. He's a superhero version of Grover and superheroes have alternate real identities. Both the real identity and the superhero identity count as two completely different characters though it's the same person. Though you could list an example like this: Bruce Wayne, Batman; but they're still two different people even though it's the one person playing both roles.
A small explanation like would justify it in your opinion? Alistair Cookie, from Monsterpiece Theater?
For references to my masterpiece of Muppets, check out a thread called "Muppet Listings 4.0" buried in the Classic Muppets section of this forum. Try looking for it around my birthday's date: December 20, of last year. Hope this helps.
