Armordillo (3.5e Monster)

"Martha...I just broke my sledgehammer on thet critter's head. Time to call the professionals..."

The Armordillo appears to be a normal armadillo in all respects except 3:

It is a voracious devourer of vegetable crops. It is incredibly heavy (200+ pounds) for it's size. It has no fear.

Whether it was created, or evolved naturally, 10 out of 10 farmers agree the Armordillo has to go. The problem is how. The things are damn near invulnerable, so unless they're willing to shell out serious money for help, they're stuck with them.

Combat
Armordillo's never initiate combat. They go about their business of devouring crops, and sometimes even ignore attackers if they can't manage to do any damage. The sight of a bunch of villagers breaking their farming tools on the back of a small critter has stunned more than one PC. Usually just before desperate villagers agree to pay them to remove the things. They're less of a hazard or wandering monster, and more of a stubborn obstacle. Note that they were made for my Silly Campaign, and aren't meant to be a fight so much as low level PC's figuring out how to deal with the immovable object.

Invulnerability: Invulnerability is similar to Damage Reduction, but it also blocks damage from energy attacks, spells, spell-like abilities, and supernatural abilities.

Immunities: The Armordillo is immune to Fear or morale based effects. It is also immune to non lethal damage, and cannot be Stunned, Dazed, or Staggered.

Fortified: If an enemy confirms a critical result on an attack roll the Armordillo has a 50% chance of making it just a normal hit.

Hard to Budge: The Armordillo does not take a Size Penalty when resisting Grapple, Bull Rush, or Trip checks. It also has a +4 Racial Bonus when resisting such checks.
