After reaching the Mass Fusion Building, head inside (if you haven't already cleared it, it will be full of Raiders, so be wary!). Make your way up to the top level, where you fight the Raider leader wearing Power Armor. The Bobblehead is sitting on the top of the statue hanging over the lobby - climb onto the couch to collect it.

Head to the south-east corner of the map to reach Poseidon Energy. You'll find the Bobblehead inside the central chamber, which is a large open area with, several stories tall. Use the ramps and scaffolding to get up to the room that's elevated in the middle, and you'll find the Bobblehead along with several enemies.

In the northern section of The Commonwealth, make your way to the Parsons Asylum. If you haven't started the Quest chain for Mr. Cabot, you wont be able to get in.

To enter the Asylum, you must be at least level 10, and fight some of the Mercenaries guarding the Asylum. Then look for a Ghoul named Edward Deegan, who travels between several bars in the Diamond City Market, Goodneighbor, and Bunker Hill. Once he introduces you to his boss at the Cabot House, complete the chain of quests until you enter the Asylum with Mr. Cabot.

Once inside, fight off the raiders and follow Mr. Cabot to his office, where you will find the Bobblehead on his desk.

Fight your way through the Protectrons, turrets and Super Mutants until you reach the large room on the north side of the library's second floor. At the far end of this chamber is a wooden door - pass through it to find the Bobblehead resting on the computer console in the next room.

Enter the belly of the Northern Star and cross the piles of cargo containers to the stern of the ship. Make your way up to the main deck, then head to the bow. After moving up the stairs into the makeshift hut, you will find the Bobblehead on the very edge, sitting on a small beam.

Once you reach Spectacle Island, make your way towards the southern shore. Past a small dilapidated hut, a derelict green tugboat lies beached in the shallows. The Bobblehead can be found by entering the wheelhouse of the boat and searching the locker next to the steamer trunk.

Enter the cannery and go to the assembly room. Follow the catwalks up and around to the right (to the north side of the building), then enter the room that overlooks the assembly line to find the Bobblehead.

After fighting your way into and clearing Vault 95, head through the door on the right side of the main chamber, then down to the lower residence via the doorway at the end of the hall. Move through the destroyed wall at the bottom of the ramp and go through the door on your right, eliminating any remaining Raiders, and find the Bobblehead on the radio between the two couches in the next room.

In the Command Center section of Fort Hagen, you will find this Bobblehead in the kitchen area, sitting between two refridgerators on your way towards the basement tunnels. Note that you will not be able to access the elevator leading to the Fort Hagen Command Center until you begin the main quest, Getting a Clue in Diamond City.

Upon reaching the Ironworks, fight your way through the Forgers outside and in the first two chambers. Make your way up the destroyed catwalks in the second room and follow them to reach the doors to the Blast Furnace. Once inside the Blast Furnace area, you can this Bobblehead sitting upon a tall computer, directly behind where Slag stands during your confrontation.

Head down through the Gallery to it's lowest levels. You will eventually come across a man, Pickman, being held up by raiders. In this room is a flaming trashcan in the center of the room. Beside it you will find the Bobblehead.

In Vault 81, take the elevator down to the basement level. Inside the medical area, with the floating robot Curie, you will see this Bobblehead.

In the cage where Rex and Strong are being held, at the very top of Trinity Tower. To get there, you will need to go up a couple elevators, before finally reaching the top floor, which is basically an exposed, roof like area.

Inside Vault 75 (aka Malden High School), head to Basement Level 3. While down here, you will find a room that overlooks the cavern with the run down stores. Inside this room is the Bobblehead.

Inside the building, there is a room with a sign above the doors saying On the Air. You will need to be able to pick Master level locks to get inside. Once in, you'll see the Bobblehead on the desk.

This is deep within the caves. You will know you're close when the enemies become Ghouls. If you get to the end though and kill several Ghouls with names, you've gone a bit too far, as the Bobblehead is about a 5 second walk back from the final room.

This is found in the Vault 114 Overseer's Office where you find Nick Valentine while pursuing the main quest, Unlikely Valentine. You'll spot the Bobblehead sitting on a desk behind him.

Look for a rusted car that's inside the main garage. On its hood will be the Bobblehead.
