D&D 30 Day Challenge - Favorite Monster Overall - Tarrasque

I've never ran this sombitch! but damn it I want to! AC - 3, 300 HPs!!! approx 70 HD, HOLY CRAP ON A CRACKER, the heroes' better be gods. The XP value is a whooping 107,000, a guaranteed level advancement right there, provided you don't die!  

"Okay gents I'm going to need about 60 potions of healing, a couple of giant henchmen, a wizard with a wish spell, and a bit of luck".

So the question that comes to my mind is, has anybody ever actually unleashed this guy???? Please tell me! hahaha

Seriously I think I'd get tired of rolling damage, 300 HPs!!! This would make for an interesting campaign.  obviously you'd have to seriously equip the PC's, and start off with some high level peeps.  Their deaths would be legendary! Minstrel's would right songs about how it ripped there flesh apart, and made stew.  

Anther thing I've always thought is that the Tarrasque, looks quite a lot like Doomsday, the guy that killed Superman. 

A little info - The legendary tarrasque, for there is fortunately only one known to exist, is the most dreaded monster native to the Prime Material plane. The creature is a scaly biped with two horns on its head, a lashing tail, and a reflective carapace.  Slaying of the tarrasque is said to be possible only if the monster is reduced to -30 or fewer hit points and a wish is then used. Otherwise, even the slightest piece of the tarrasque can regenerate and restore the monster completely.  Note: Creatures with a minus THAC0 can only be hit on a 1.  More info on the Tarrasque here - http://www.lomion.de/cmm/tarrasqu.php 

The tarrasque is a gigantic lizard-like creature which exists only to eat, kill and destroy. In most campaign settings, only one tarrasque is said to exist on each world. The tarrasque has a low intelligence and cannot speak. It is neutrally aligned, for despite its violent and savage nature, it lacks the mental capacity to choose between good and evil.

The tarrasque was introduced to the D&D game in the first edition of Advanced Dungeons & Dragons. It is based upon the French legend of the tarasque.  

Here's a bit of Tarrasque humor for you, (can't believe it was on cheeseburger!)
