Special Abilites

Amorphous. The ooze can move through a space as narrow as 1 inch wide without squeezing.
Corrode Metal. Any nonmagical weapon made of metal that hits the ooze corrodes. After dealing damage, the weapon takes a permanent and cumulative −1 penalty to Damage rolls. If its penalty drops to −5, the weapon is destroyed. Nonmagical ammunition made of metal or wood that hits the pudding is destroyed after dealing damage.
The ooze can eat through 2-inch-thick, nonmagical metal in 1 Round.
False Appearance. While the ooze remains motionless, it is indistinguishable from an oily pool or wet rock.

Actions

Pseudopod. Melee Attack: 1d20+2 to hit, reach 5 ft., one target. Hit: 4 ( 1d6+1 ) Bludgeoning Damage plus 7 ( 2d6 ) Acid Damage. In addition, nonmagical metal armor worn by the target is partly dissolved and takes a permanent and cumulative −1 penalty to the AC it offers. The armor is destroyed if the penalty reduces its AC to 10.
