Yep, you found it Psi. Now that I've seen that, I wouldn't allow it in my games because it specifically says no.
Polymorph: a polymorph spell transforms your physical body to  take on the shape of another creature. While these spells make you  appear to be the creature, granting you a +10 bonus on Disguise skill  checks, they do not grant you all of the abilities and powers of the  creature. Each polymorph spell allows you to assume the form of a  creature of a specific type, granting you a number of bonuses to your  ability scores and a bonus to your natural armor. In addition, each  polymorph spell can grant you a number of other benefits, including  movement types, resistances, and senses. If the form you choose grants  these benefits, or a greater ability of the same type, you gain the  listed benefit. If the form grants a lesser ability of the same type,  you gain the lesser ability instead. Your base speed changes to match  that of the form you assume. If the form grants a swim or 
burrow  speed, you maintain the ability to breathe if you are swimming or  burrowing. The DC for any of these abilities equals your DC for the  polymorph spell used to change you into that form. In addition to these benefits, you gain any of the natural attacks of  the base creature, including proficiency in those attacks. These  attacks are based on your 
base attack bonus, modified by your 
Strength or 
Dexterity as appropriate, and use your 
Strength modifier for determining damage bonuses.
 If a polymorph spell causes you to change size, apply the size modifiers appropriately (see 
Table: Ability Adjustments from Size Changes), changing your 
armor class, 
attack bonus, 
Combat Maneuver Bonus, and 
Stealth skill modifiers. Your ability scores are not modified by this change unless noted by the spell.
 Unless otherwise noted, polymorph spells cannot be used to change  into specific individuals. Although many of the fine details can be  controlled, your appearance is always that of a generic member of that  creature's type. Polymorph spells cannot be used to assume the form of a  creature with a template or an advanced version of a creature.
 When you cast a polymorph spell that changes you into a creature of the 
animal, 
dragon, 
elemental, 
magical beast, 
plant, or 
vermin  type, all of your gear melds into your body. Items that provide  constant bonuses and do not need to be activated continue to function  while melded in this way (with the exception of armor and shield  bonuses, which cease to function). Items that require activation cannot  be used while you maintain that form. While in such a form, you cannot  cast any spells that require material 
components (unless you have the 
Eschew Materials or 
Natural Spell feat), and can only cast spells with somatic or verbal 
components  if the form you choose has the capability to make such movements or  speak, such as a dragon. Other polymorph spells might be subject to this  restriction as well, if they change you into a form that is unlike your  original form (subject to GM discretion). If your new form does not  cause your equipment to meld into your form, the equipment resizes to  match your new size.
 While under the effects of a polymorph spell, you 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. While most of these should be  obvious, the GM is the final arbiter of what abilities depend on form  and are lost when a new form is assumed. Your new form might restore a  number of these abilities if they are possessed by the new form.
 
You can only be affected by one polymorph spell at a time. If a new  polymorph spell is cast on you (or you activate a polymorph effect, such  as wild shape), you can decide whether or not to allow it to affect  you, taking the place of the old spell. In addition, other spells that  change your size have no effect on you while you are under the effects  of a polymorph spell.
 If a polymorph spell is cast on a creature that is smaller than Small  or larger than Medium, first adjust its ability scores to one of these  two sizes using the following table before applying the bonuses granted  by the polymorph spell.
