Bobblehead - Strength

Bobblehead - Strength is a Fallout 3 item, a Vault Boy Bobblehead. It permanently improves your character's Strength by 1, to a maximum of 10.

Location
The bobblehead is found in Lucas Simms' House in Megaton, on a desk in the bedroom (door to immediate left at top of stairs) on the second floor.

Ways of Entering Lucas' home
An easy way to enter Lucas' home is to loot the key to his home. One way of looting the key is as follows. After Mr. Burke asks you to blow up Megaton, go tell Lucas what he said. Lucas will then head over to Moriarty's saloon to handle Mr. Burke. Lucas and Mr. Burke will enter and shoot-out and, if you do not kill Mr. Burke yourself, then Mr. Burke will kill Lucas. You can then pluck the key to Lucas' house off Lucas' corpse, along with his Sheriff's Duster and Sheriff's Hat.

You can pickpocket the key off Lucas. However, you will lose karma this way.

The door to Lucas' home needs an Average level of Lockpicking skill. If you are spotted while breaking in, all of the residents of Megaton will turn hostile. You'll also lose karma if you lockpick the door.

If you wait until Lucas goes home, you can then enter the house without loss of karma, and take the bobblehead while he eats downstairs.

If you want to acquire the bobblehead without needing to wait for Simms to go inside, do the following. Carry an empty metal drum over to the railing between the Water processing plant and Lucas Simms' house. Jump on top of the metal drum and then jump onto Lucas' roof. Enter his home via the roof hatch door.
