Vault-Tec Bobblehead

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

In Fallout 3, each of these bobbleheads permanently increases one of the 7 statistics(S.P.E.C.I.A.L) or one of the 13 skills of the Player Character. Two of the Fallout 3 achievements are about collecting 10 or 20 of them.

The bobbleheads which raise SPECIAL scores will not increase a statistic over the normal maximum of 10. If your score in the relevant SPECIAL statistic is already 10, the extra point will be wasted. Likewise, the skill bobbleheads cannot raise your skill past 100, and additional points will be wasted.

The player can store the bobble heads on a special stand found in the player's owned house.
