A Turkey Day Feast!

Next week is Thanksgiving, so I've decided to cook up some holiday fun to share with you. First, I'll present Pathfinder stats for turkeys, then I'll mutate the hell out of one (literally).

A turkey can easily be represented by adding the giant simple template (Bestiary 294) to a chicken (Familiar Folio 24):

TURKEY (CR 1/3)

XP 135
N Small animal
Init +3; Senses low-light vision; Perception +5

Defense
AC 13, touch 10, flat-footed 13 (-1 Dex, +3 natural, +1 size)
hp 7 (1d8+2)
Fort +5, Ref +1, Will +1

Offense
Speed 30 ft., fly 20 ft. (clumsy); drift
Melee bite -1 (1d4-2)

Statistics
Str 7, Dex 9, Con 16, Int 2, Wis 12, Cha 13
Base Atk +0; CMB -2; CMD 6
Feats Improved Initiative
Skills Fly -7, Perception +5

Special Abilities
Drift (Ex) A turkey flies in short bursts, and can't use its fly speed to hover. When it flies, a turkey must end its action by landing or perching on a solid surface.

Wild turkeys are more agile fliers than their plump, well-fed, domesticated kin: improve maneuverability to poor and Fly skill to -3, and remove the drift special quality. 

Turkeys are hardly threatening, even to low-level characters. But Green Ronin's Advanced Bestiary contains numerous templates that can change this feeble poultry into a truly nightmarish beast. The Great Gobbler of Shibaxet is an abomination unleashed upon the mortal world by the cult of Pazuzu, the demon prince of evil avians (Bestiary 4 50). Its sole purpose in life is to devour all creatures smaller than itself.
