Barrel of monkeys is awarded randomly while skilling or like a drop from Clawdia throughout the Summer Beach Party at stacks of 5. It could be dropped over a surface (#( excluding bank areas )#) in runescape 3 gold , releasing numerous grey, scampering monkeys (#( around 10, each monkey lasts roughly half a minute before disappearing )#) which move about randomly.

It may only provide once, because the barrel will disappear with all the monkeys after use. It is possible to only place 1 barrel at any given time. No warning message has before it is used.
While functionally just like the Squeal of Fortune version, it is tradeable.
