When you squeeze this 2-3/4" diameter Monkey Groan Ball it emits what can be described as the groans of a monkey that has been inhaling helium. Not only does this pliant rubber monkey ball marvel reduce stress while it amuses you, but keeping a disembodied monkey head on your desk serves as a warning to other primates of what will happen if they cross you. Hilarious!
