Vault-Tec Bobblehead

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

Each of the twenty Vault Boy bobbleheads in Fallout 3 permanently increases one of the 7 statistics (S.P.E.C.I.A.L.) by one point or one of the 13 skills of the Player Character by 10 points.

Each bobblehead you find can be placed on your Bobblehead Collector's Stand

In the case that the bobblehead is located inside a currently owned building there will be no karma penalty for taking it nor any risk of turning the town inhabitants onto you either.

The bobbleheads will not increase a statistic beyond the maximum of 10 (S.P.E.C.I.A.L.) or 100 (skills). Keep that in mind when planning your character, or their bonus might be wasted.

Players can store the bobbleheads they have found in their house in Megaton or in their Tenpenny Tower Suite. Two of the Fallout 3 achievements and 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.

Stats
These increase the listed S.P.E.C.I.A.L stat by 1 point (to the maximum of 10). Every individual page includes a video for location.

Side note for cheating in the PC version: In order to gain any stat raises from a bobble head they must be picked up from the game world, rather than added to your inventory. To get the stat increase without finding the bobble head, it is recommended that you zoom out, go into the console, click yourself, then type "player.placeatme [object id of desired bobblehead]" in the console. This should spawn the bobble head at your feet where you can easily pick it up and get the stats.

Skills
These increase the listed skill by 10 points (to the maximum of 100). 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.
