I don't understand the mechanical aspects of the baleful polymorph spell. It works like beast shape III except that it only serves to turn your target into a small animal.
Okay, so assuming that the target fails its Fortitude save, but makes its Will save, what happens to the creature mechanically? What is its AC? Can it speak? Can it cast spells or use Spell-like Abilities?
In my Red Hand of Doom campaign, the party wizard previously turned a dragon into a sparrow and I winged the results (no pun intended). Now he's done it again to a barbed devil, turning it into a bunny. I assume it no longer has spines and a "barbed defense". Can it use the barbed devil's SLA's Can it talk?
If it passes a Fort save, nothing happens. If it fails, it must make a Will save. If it passes the Will save, it's a bunny rabbit in its physical stats (so no barbs) but it keeps its spell-like abilities - as specified in the spell. If it fails the Will save, it becomes a rabbit mentally as well - it can't even understand language.
For the druid's Wild Shape ability, it likens it to Beast Shape, but adds that you can't speak while using it, implying that with other polymorph effects, you can speak. (See also the polymorph rules p211-212; a disadvantage of using Baleful Polymorph on enemies is that their equipment is melded into their bodies, making it hard to loot them.)
The bestiary has stats for bat, lizard, rat, raven, toad and weasel under Familiar - you could use any of them for calculating AC. Let's say a rat is closest to a rabbit. AC is then 14.
However, it keeps its hit dice, so it becomes a twelve hit dice rat/rabbit with around 48HP.
(Edit: The reply below is probably more correct.)
1) Select in which " Small or smaller animal of no more than 1 HD" the target is polymorphed;
2) The target "lose all extraordinary and supernatural abilities that depend on your original form (such as keen senses, scent, and darkvision), as well as any natural attacks and movement types possessed by your original form. You also lose any class features that depend upon form, but those that allow you to add features (such as sorcerers that can grow claws) still function."
3) The "gain any of the natural attacks of the base creature, including proficiency in those attacks." and "If the form you assume has any of the following abilities, you gain the listed ability: climb 30 feet, fly 30 feet (average maneuverability), swim 30 feet, darkvision 60 feet, low-light vision, and scent" (from Beast shape I), "climb 60 feet, fly 60 feet (good maneuverability), swim 60 feet, darkvision 60 feet, low-light vision, scent, grab, pounce, and trip" (from Beast shape II) and " burrow 30 feet, climb 90 feet, fly 90 feet (good maneuverability), swim 90 feet, blindsense 30 feet, darkvision 60 feet, low-light vision, scent, constrict, ferocity, grab, jet, poison, pounce, rake, trample, trip, and web" (from Beast shape III).
4) You change the target characteristic as follow: "Small animal: If the form you take is that of a Small animal, you gain a +2 size bonus to your Dexterity and a +1 natural armor bonus.", "Tiny animal: If the form you take is that of a Tiny animal, you gain a +4 size bonus to your Dexterity, a –2 penalty to your Strength, and a +1 natural armor bonus." or "Diminutive animal: If the form you take is that of a Diminutive animal, you gain a +6 size bonus to your Dexterity, a –4 penalty to your Strength, and a +1 natural armor bonus."
Edit: I hadn't included tiny
5) If the initial shape was smaller than small or larger than medium you apply this table changes too:
Creature's Original Size Str Dex Con Adjusted Size
Fine +6 –6 — Small
Diminutive +6 –4 — Small
Tiny +4 –2 — Small
Large –4 +2 –2 Medium
Huge –8 +4 –4 Medium
Gargantuan –12 +4 –6 Medium
Colossal –16 +4 –8 Medium
Let's look at our barbed devil, because dragons are wonky. He fails his fort save but makes his will save and becomes a bunny. Rabbits are probably size tiny (about the size of a housecat), so his strength drops by 2, his dex goes up by 4, and he gains +1 natural armor. This gives him a strength of 21 and dex of 27. The end result would look something like this:
Str 21, Dex 27, AC 31 (+8 dex, +11 natural, +2 size)
CMB +15 (+19 grapple), CMD 33
Melee attack bonus: +15 (but no melee attack abilities, see below)
He loses his natural attacks for being a barbed devil and gains none, since rabbits don't have natural attacks worth speaking of.
He also loses "all extraordinary and supernatural abilities that depend on [his] original form", so Barbed Defense, Fear, Grab and Impale are all out. However, he retains his SP abilities, and may continue to use them.
Rabbits do not have the ability to speak, so the barbed devil does not either. It should be noted that Spell-like Abilities have no somatic or verbal components, and therefore can be used in devil or bunny form with the same ease.
Otherwise, everything else pretty much stays the same. All of its feats and skill remain (adjusted to the new ability scores), HD, HP, saves (again, adjusted), DR, resistances, immunities, known languages and ability to communicate telepathically.
His base speed may or may not change. I am unsure the base speed of a rabbit in Pathfinder, as I cannot find a proper analogue in a printed sourcebook. A sprinting rabbit is faster than a sprinting human, so the base speed might increase to 40.

lost Barbed Defense (Su) A creature that strikes a hamatula with a melee weapon, an unarmed strike, or a natural weapon takes 1d8+6 points of piercing damage from the devil's barbs. Melee weapons with reach do not endanger a user in this way.
Fear (Su) A barbed devil's fear attack affects any creature it damages with its claws. A DC 20 Will save resists this effect, otherwise the victim becomes frightened for 1d4 rounds. This is a mind-affecting fear effect. The save DC is Charisma-based.
lost Grab (Ex)A barbed devil can use its grab attack against a foe of up to Medium size.
lost Impale (Ex) A barbed devil deals 3d8+9 points of piercing damage to a grabbed opponent with a successful grapple check.

A hell of a rat :-)
I could have missed something, but not much. [corrected for tiny and not diminutive]
Mauril, natural armor bonuses don't stack
And a rabbit bite can damage you, especially with a strength of 21 behind it.
DR 10/good; Immune fire, poison; Resist acid 10, cold 10; all depend on the original form.
SR 22 probably it stay, you are right.
How can there possibly be a thread about a devil turned into a bunny with a 21 Str, DR, Spell and Energy Resistance and yet not a single Monty Python reference in the thread yet?!?
OK - "That rabbit's dynamite!"
If it makes the will save after failing the fort save...
What is its AC?
10+new dex mod + new size mod +ring of deflection + any spells on it +the natural ac from wildshape. They loose their armor bonus and their own natural armor bonus.
Can it speak?
No. Under the polymorph rules you are limited to the sounds an untrained animal of your new type can make, so you're stuck growling and squawking.
Can it cast spells
Only if it has natural spell, or it can use all the components of its new form. Someone polymorphed into a raccoon that can borrow a spell component pouch can probably pull off Silent spells. Someone polymorphed into a pig will need a silent, stilled spell.
or use Spell-like Abilities?
Yes. They activate by force of will, which the character still has if they've made the will save.
Edit: I see I mistyped some text in the AC comment:
[the natural armor bonus is tricky. As written it should not be reduced as it is not a SU or EX ability, but I feel it should be replaced by the new natural armor bonus. Note that a natural armor bonuses don't stack with another natural armor bonus, so he would have either +1 or +10, not +11]
Hmm, the devil subtype don't give any DR.
and I would say that independently from him retaining his subtype the immunity and resistances are linked to his physical make up, not to him being part of a race.
A Elf is a subtype of the humanoids, but he would lose low light vision.
Now the question is, did Pathfinder make polymorphing more confusing or less confusing than 3.5?
More confusing in regards to negative polymorph effects like baleful polymorph, as well as polymorph any object. Everything else polymorph is absolutely less confusing.
