Bobbleheads are one of the types of collectibles in Fallout 4. They have the same purpose as in Fallout 3. It means that each time you've found a bobblehead and picked it up you'll receive a permanent increase to one of your statistics. This can make a huge difference, especially in the early pars of the game. Make sure to collect the bobbleheads which are easy to acquire as soon as possible. Some of them will require you to unlock advanced perks or to visit more dangerous locations and you can leave them for later. Below is the list of bobbleheads along with the info on where exactly you can find them.
