Black puddings are the scavengers of the underworld, constantly on the lookout for a meal. They can sense organic or metallic objects within 60 feet and mindlessly attack such items or beings until they are dissolved or the ooze is killed. A black pudding reproduces by breaking off a piece of its body and forming a new, smaller black pudding, which grows to full size in 1 month's time. Some of the more intelligent creatures in the underworld use black puddings as natural garbage disposals, creating stone pits to house the pudding and throwing organic refuse or foes in as needed.
Larger specimens of black puddings have been encountered in the deepest parts of the world, with Gargantuan individuals having up to 30 HD. Other colored puddings are rumored to exist, with white ones living in the arctic, brown ones living in swamps, and tan ones living in deserts.
constrict (2d6+4 plus 2d6 acid)
Corrosion — An opponent that is being constricted by a black pudding suffers a –4 penalty on Reflex saves made to resist acid damage applying to clothing and armor.
ooze traits
Suction — The black pudding can create powerful suction against any surface as it climbs, allowing it to cling to inverted surfaces with ease. A black pudding can establish or release suction as a swift action, and as long as it is using suction, it moves at half speed. Because of the suction, a black pudding's CMD score gets a +10 circumstance bonus to resist bull rush, awesome blows, and other attacks and effects that attempt to physically move it from its location.
Grab
(slam)
Ex
from Universal Monster Rule
If a creature with this special attack hits with the indicated attack (usually a claw or bite attack), it deals normal damage and attempts to start a grapple as a free action without provoking an attack of opportunity. The creature has the option to conduct the grapple normally, or simply to use the part of its body it used in the grab to hold the opponent. If it chooses to do the latter, it takes a –20 penalty on its combat maneuver check to make and maintain the grapple, but does not gain the grappled condition itself. A successful hold does not deal any extra damage unless the creature also has the constrict special attack. If the creature does not constrict, each successful grapple check it makes during successive rounds automatically deals the damage indicated for the attack that established the hold. Otherwise, it deals constriction damage as well (the amount is given in the creature's descriptive text). Creatures with grab receive a +4 bonus on combat maneuver checks made to start and maintain a grapple. Unless otherwise noted, grab works only against opponents no larger than the same size category as the creature. If the creature can use grab on sizes other than the default, this is noted in the creature's Special Attacks line.

from Universal Monster Rule
A creature with this special attack can crush an opponent, dealing bludgeoning damage, when it makes a successful grapple check (in addition to any other effects caused by a successful check, including additional damage). The amount of damage is given in the creature's entry and is typically equal to the amount of damage caused by the creature's melee attack.
