Sometimes you just need to visit Age of Fable to get a good random creature.

Here the link to the random generator.

Saying only that the creature should resemble an armadillo...

Capreotetra, or Shadow Protector
This creature is large (at least twice the size of a human).
They live in arctic regions.
They will typically be found alone, or in a group (or cluster) of two or three.
The Capreotetra looks like a wooden carving of an armadillo.
They're a type of Animate (see below).
They have human-like intelligence.
Magnetic: The creature is magnetic. Metal items (including armour) will be dragged towards it. In the case of weapons, this may cause the creature significant harm.
Natural Armour: The creature's hide is so tough that it's treated as armour. This doesn't stop the creature having actual armour as well, if appropriate.
Immunity to Poison: The creature is totally immune to poison.

Triealian, or Ancient Warrior
This creature is roughly the same size as a human.
They live underground. They travel through the earth like a fish through water or a bird through the air.
A typical group, or cluster, consists of 1-6 creatures.
The Triealian looks like an armadillo, but fiery and demonic.
They're a type of Spirit (see below).
They have only animal-like intelligence.
Immune to Physical Harm: The Spirit is immune to non-magical harm (for example from normal weapons).
Greater True Sight: The creature is totally immune to magical attacks based on illusions or fear.

Atlanvore, or Folk-o'-the-Isles
This creature is roughly the same size as a human.
They live in the sea.
A typical group, or den, consists of 1-6 creatures.
The Atlanvore looks like a dice which has grown into the shape of an armadillo.
They're a type of Folk (see below).
They have human-like intelligence.
Amphibious: The creature can breathe both water and air (or in the case of Animates, their mechanisms are waterproof).
Swallow whole (lesser): The creature has a chance of swallowing any enemy which is roughly half its size or smaller. The victim will eventually die. They can't attempt to break free - they can only be saved if the creature dies. The creature will dissolve armour first, and only then start to damage the character. The creature's stomach doesn't dissolve metal. It will never swallow characters with metal armour (or Animates made of metal).
Resistant to Poison: The creature is less effected by poison than a normal creature of its type would be.
Paralysis: The creature's attack involves a particular kind of poison which may cause paralysis, until the poison is removed or a natural or magical antidote can be applied.
