Barrel of Monkeys

This item is a small keg weighing only 5 lbs when activated, it will burst open, spewing out a pack of rampaging monkeys who will immediately begin climbing over everything, hooting, howling, shrieking, flinging poop, and stealing anything they can carry. When the item is activated, roll 1d4. On a roll of 1, the barrel will summon 4D6 small-sized spider monkeys, on a 2 it summons 3D6 howler monkeys, on a 3 it summons 2D6 chimpanzees, and on a 4 it summons 2D4 Orangutans. The monkeys will rampage for one hour, then disappear. The Barrel of Monkeys is destroyed once used.
