Bobblehead - Unarmed

Bobblehead - Unarmed is a Fallout 3 item; a Vault-Tec bobblehead. It permanently improves your character's Unarmed skill by 10. Unarmed damage increases with skill levels over 100 so this is useful even after leveling unarmed to 100.

Inside a cave directly north of Girdershade and directly west of Smith Casey's Garage. In a forked valley which is a "random encounter" location, look for a big rock under a string of tattered black banners.
 * At night, light visibly emits from the rock, making it easier to spot.
 * The bobblehead is found on the ground next to a dead ghoul. The cave is actually Rockopolis, notably mentioned in the tales of Herbert "Daring" Dashwood; and the dead ghoul is his manservant, Argyle.
