Album Cover Roll Call? Edit

Would it be possible for someone to add a caption under the photo of this album's cover, identifying all the characters who appear on it? From top left to right, I recognize Frazzle, Herry, Cookie and Grover, but who's the green one in the upper right? (It looks a little bit like Arlene Frantic with a nose.)

I'm especially interested in knowing the name (if there is one) of the purple monster in the lower left corner. This monster makes a cameo appearance in the "Grover and the Everything in the Whole Wide World Museum." storybook, and I'd like to get its name added to the list of characters appearing in that book, if possible.--5:00weasel 23:04, January 15, 2011 (UTC)

Well, we don't usually put captions under album covers, but you're welcome to add who appears on the cover in the text section. And maybe one of our monster experts will be able to figure out the ones you don't know. -- Ken (talk) 00:11, January 16, 2011 (UTC)
