Vault-Tec Bobblehead

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

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

The bobbleheads will not increase a statistic beyond the maximum of 10 (S.P.E.C.I.A.L.) or 100 (skills).

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 involve collecting Vault Boy Bobbleheads. The first achievement is awarded for collecting 10 of them, and players earn the second for finding 20 of them.

Stats
These increase the listed S.P.E.C.I.A.L stat by 1 point (to the maximum of 10).

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

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.
