Bloated zombies are similar to normal zombies except for their bloated, distended tissues under their greenish skin, especially around the abdomen. While still animated they fight much like normal zombies, losing intiative and attacking last with their rotten hands. When they are slain, however, they explode in a disgusting and messy way, spraying anyone in a 10' radius (including anyone in melee range) with gangrenous acidic fluids. This causes 1d6 acid damage to each creature in range.

Bloated zombies are not immune to each others' acidic fluids, so one exploding may cause another nearby bloated zombie to explode – possibly setting off a vile chain reaction. As they are mindless and have no sense of self-preservation they will not avoid this.
Like other zombies, bloated zombies are undead, and thus immune to charm, sleep and other mind-affecting spells, as well as poison and disease. They can be turned as if they were ghouls.

Bone warriors are the animated remains of experienced fighters, and some skill seems to have somehow lingered in the bones. Bone warriors are superior in combat to normal skeletons. It is unknown exactly how clerics of Chaos manage to create these variants, but even casual observation shows that they move in a more steady and purposeful way than other animated undead. Bone warriors wear armour and some sort of weapon, usually a sword. They are often found in small squads, assigned specific duties too important to be left to normal skeletons. Their modicum of intellect is used in combat for tactics that normal skeletons would not think of. Bone warriors are undead and thus immune to charm, sleep and other mind-affecting spells, as well as poison and disease. They can be turned as wights by clerics.

Skeletal rats are the animated remains of giant rats, and are about the size of small dogs. Although one on its own is little threat to a party of adventurers they are nearly always found in packs up to 20 strong, and as such they may overwhelm with sheer numbers. They are created using dead giant rats and a cleric with Animate Dead spells and as such are usually found in chaotic temples or cursed crypts. They have a tendency to attack and kill any living thing, even living giant rats. 

Like other skeletons, skeletal rats are undead, and thus immune to charm, sleep and other mind-affecting spells as well as poison and disease.

Zombie wolves are the animated remains of wolves, coyotes and large domestic dogs, created by chaotic and despicable spellcasters using Animate Dead spells. Although they attack slower than living wolves (like other zombies they attack last in each round), they can still lope around as fast as a human can run, and therefore are used when humanoid zombies are too slow. Zombie wolves are of course undead and thus immune to charm, sleep and other mind-affecting spells, as well as poison and disease. They can be turned by clerics as if they were ghouls.
