Extinct Muppets?

[SeanC]

And by 'extinct', I mean 'no longer in existence'.

Just curious if anyone has a definite list of which Muppets still exist and which ones have decayed/fallen into extreme disrepair?
I'm particularly interested in the fate of the full-bodied suits.

Sweetums - still active, although I assume the suit has been updated many times since the 70s.
Thog - missing since the early 80s, strongly rumored to be dead.
Doglion - last appearance was 'Muppets Tonight' in the late 90s.
Timmy - last appearance 'The Jim Henson Hour' late 1980s (?)
Mean Mamma - was she ever seen after TMS?
The Mutations - lost in action 1980s.
Fletcherbird - last seen at the Royal Variety Show 1993 ( although the suit looked in reasonably good condition ).
Betsy Bird - missing since early 80s.
Thig - long dead I'd imagine.
Bobo - still active as of 2009.
Splurge - long gone, I'm guessing.

Just curious if anyone knows for sure.

I don't know. Sweetums appeared in Muppets Treasure Island, but I've also always wondered where the Mutations went.

The Hugga Wugga muppet is something I'm interested in. Maybe they can put Hugga on Sesame Street, with a few modifications (i.e. friendlier eyes, neat eyebrows, and speaks in full sentences.) He could be the SS equivelent to, hmm- perhaps Sweetums?
You know, a friendly monster, occasionally clumsy. You and I, besides 'controling my 'Hugga Wugga Fear'' could work on a project, trying to get Hugga on Sesame Street, as maybe a friend of Elmo's, and even in the latest SSL show! This is gonna be awesome!
