Looking for giant crab stats

[Hand_of_Vecna]

I'm looking for the stats on the dire/giant/monstrous (don't remember which) crab that was posted on an official wizards site. This is to show someone for it's wtf value not for a game so I'm only interested in the official monster not a reasonable homebrew or a pathfinder crab or anything else similar.

I remember it was CR 2 with over 30 hp two attacks that could one shot a max hp lvl 2 fighter, an AC close to 20, vermin(immune to mind effecting spells) and had a 40 movement rate so you couldn't even run away.

My google fu is failing me though.

That damn crab! (http://www.wizards.com/default.asp?x=dnd/fw/20040221a)

Weak Point (Ex): If the crab is struck in its weak point, it takes massive damage.

Oh come on, we were all thinking it.

For the record, 3.5 has in "Stormwrack" a much more reasonable giant crab enemy.

Warning, Greenish's crab is a great way to TPKO

Bards may not be the strongest dip, but the soundtrack will be awesome. (http://www.youtube.com/watch?v=JMNSjxrBZto&feature=related)

Also, butter deals double damage against the beast.

Only if it's given the Flaming ability.

I don't suppose there's something similar but stronger. I'm playing X-crawl (so limited room) and I want one for a mount. The weirdness works very well with my armoured cowboy bard.

It needs to be large decent hp about 100 will do.
