The Noisemaker is a utility item that can be found by playing a level or buying it in the store in Robbery Bob 2: Double Trouble. Once activated, the player must wait to finish its countdown in order for it to make noise. It is similar to the Wind-up Toy, except the fact that it can lure NPCs to where it is placed.
This loud Noisemaker is a sure way to attract someone's attention.
The player can either play more to get it for free or buy a set of 2 Noisemakers with real-life currency.
