tom bombadil could be in this one. personally, i think he should be played by the "post-christmas" grinch or any one of the whos.
yes, i am well aware that he is not a muppet, this idea came to me in the middle of the night. but there is an explanation: to me, bomabadil is the most random character in the book, thus explaining the grinch. & the rhyming? well, it's dr. seuss, all those people do is rhyme!
well...it made sense to me.
