The pudding can move through a space as narrow as 1 inch wide without squeezing.
A creature that touches the pudding or hits it with a melee attack while within 5 feet of it takes 4 (1d8) acid damage. Any nonmagical weapon made of metal or wood that hits the pudding 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 pudding can eat through 2-inch-thick, nonmagical wood or metal in 1 round.
The pudding can climb difficult surfaces, including upside down on ceilings, without needing to make an ability check.
The pudding regains 10 hit points at the start of its turn. If the pudding takes fire damage, this trait doesn't function at the start of the pudding's next turn. The pudding dies only if it starts its turn with 0 hit points and doesn't regenerate.
Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 6 (1d6 + 3) bludgeoning damage plus 18 (4d8) acid damage. In addition, nonmagical 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.
