Amorphous. The pudding can move through a space as narrow as 1 inch without expending extra movement to do so.
Corrosive Form. A creature that hits the pudding with a melee attack roll takes 4 (1d8) Acid damage. Nonmagical ammunition is destroyed immediately after hitting the pudding and dealing any damage. Any nonmagical weapon takes a cumulative -1 penalty to attack rolls immediately after dealing damage to the pudding and coming into contact with it. The weapon is destroyed if the penalty reaches -5. The penalty can be removed by casting the Mending spell on the weapon. In 1 minute, the pudding can eat through 2 feet of nonmagical wood or metal.
Spider Climb. The pudding can climb difficult surfaces, including along ceilings, without needing to make an ability check.
