Bobblehead - Energy Weapons

Bobblehead - Energy Weapons is a Fallout 3 item, a Vault Boy Bobblehead. It permanently improves your character's Energy Weapons skill by 10, to a maximum of 100.

Location
Found in Raven Rock on the right desk in Colonel Autumn's bedroom. After you pass the huge door from section 2B to 2C, the hallway will extend further and end with doors on the left and right. Take the left door to retrieve the bobblehead inside the room. Be sure to grab it before entering the Control Room on your way to see President Eden, as you cannot return for it once you have already done so.

The Bobblehead seems to be carrying a weapon similar to the Alien blaster.
