Vault-Tec Bobblehead

The Vault Boy bobblehead figures were promotional Vault-Tec items.

Twenty of them can be found in the Capital Wasteland.There is never any karma loss or risk of retaliation for taking a bobblehead. Once found, you can store the bobbleheads on a Bobblehead Collector's Stand in your house in Megaton or in your Tenpenny Tower Suite.

Two of the achievements/trophies involve collecting Vault Boy Bobbleheads. The first achievement or trophy is awarded for collecting 10 of them, and players earn the second for finding all 20 of them.

Effect
Each of the Vault Boy bobbleheads in Fallout 3 permanently increases one of the 7 SPECIAL statistics by one point or one of the 13 skills of the player character by 10 points. The bobbleheads will not increase a statistic beyond the maximum of 100 (stats) or 1000 (skills). Keep that in mind when planning your character, or their bonus might be wasted i.e it is inadvisable to max out any of your SPECIAL stats before leaving the vault, as any subsequently collected bobbleheads and their associated effects will go to waste.

List
Every individual page includes a video for location.

Behind the scenes
The bobbleheads were also used as a Fallout 3 promotional item by Bethesda Softworks and are included in the Collector's Edition of the game. They are identical to the ones in-game, but have arms crossed in front.
