Vault-Tec Bobblehead

Vault-Tec bobblehead figures are promotional Vault-Tec items in Fallout 3, Fallout 4 and Fallout 76. Although found in the game files, Vault-Tec bobbleheads do not appear in Fallout: New Vegas.

Background
Vault-Tec bobbleheads are found on the eastern side of the former United States, in the regions of the Capital Wasteland, the Commonwealth and Appalachia. Bobbleheads were exclusive Vault-Tec merchandise available to executive-level employees of the Vault-Tec Corporation. They were also offered as a gift to individuals who had been accepted into vaults.

Fallout 4
Each bobblehead in Fallout 4 increases a corresponding S.P.E.C.I.A.L. stat permanently by one or grants a permanent perk. They can be stored on a bobblehead stand which can be crafted at any settlement. A stand is also present in the room in Vault 81 upon being granted to the player character. Refer to the respective articles for more detailed information.

Taking a S.P.E.C.I.A.L. bobblehead while the player character's stat is at 10 allows that stat to increase to 11. As the Bobblehead counts as a stat gain, if one was below 10 before picking it up, they cannot level that stat to above ten via normal methods.

Fallout 76
Unlike other Fallout games, the bobbleheads in Fallout 76 are not permanent, and are consumables that provide temporary effects lasting one real-world hour (two hours with Curator), and multiple copies of each bobblehead can be held. There are fixed locations for a bobblehead to potentially spawn, although the ones that do are randomized.

Locations
Bobbleheads in Fallout 76 no longer spawn at a set location. Instead, they are randomized across a set number of locations. Bobbleheads are susceptible to physics, so they may fall off of platforms and may not be in the exact location. Additionally, other players may loot bobbleheads, preventing them from appearing.
