My favorites.
Kermit- Because, well, what can I say, he's Kermit. I just plain love him.
Rowlf- Because he's supportive when you need support and funny when you need to laugh. Plus he plays piano, and he looks like he gives REALLY good hugs.
Robin- Because he is just so sweet and innocent, and he knows how it feels to be ignored sometimes- something I can definately empathize with. And because of his relationship with his Uncle Kermit, which is just so sweet... wait, I already said that he's sweet... well, it's a little different... oh, you know what I mean.
