If you've been playing Fallout 3, you've probably found a few Bobbleheads tucked away on dusty shelves and desks. You'll need to collect at least ten to unlock the "Yes, I Play with Dolls" achievement and all twenty for the "Vault-Tec C.E.O." achievement. But even if you don't give a hoot about your gamer score, you'll still need to collect every one of these wobbly figurines to create the ultimate, kickass, Wasteland survivor. That's because there are seven Bobbleheads that boost your core S.P.E.C.I.A.L. stats, and thirteen that give a healthy bonus to your skills. This means you'll be able to spread out your points more every time you level-up, allowing you to max out even more skills.

Above: This is what your glorious collection will look like after following the directions in this most awesome guide 

Having trouble finding any of these stat-boosting collectibles? Read on for videos, maps, and detailed directions that explain how to find all twenty Bobbleheads. Although we've done our best to avoid any major spoilers, explaining how to find each one may reveal a few details that you may not want to see. So scroll on with care, fellow Wastelanders.

You’ll find the Strength Bobblehead in Lucas Simm’s home in Megaton. It’s the very first shack on your immediate right when you enter the city. It'll be locked, so you'll either have to pick the lock, steal the key from Lucas, kill Lucas and take the key, or get Mr. Burke to kill Lucas by reporting him. Enter the house, climb up the stairs and enter Lucas Simm’s bedroom on your left. Check the top of his desk for a boost to your Strength.

WARNING: If you’re planning to take the evil route by blowing up the city of Megaton, make sure you grab the Strength Bobblehead first! If you don’t, it’ll be blown to smithereens along with the rest of the city.

The Republic of Dave is in the far northeast corner of the world map. Enter the camp and head into the Museum of Dave on your left. You'll find the Bobblehead on the shelf to your right.

Head northwest from Paradise Falls to reach Deathclaw Sanctuary. Head down the sloping path. You’ll find the Endurance Bobblehead near the brahmin corpse.

Above: As you may have guessed, there are lots of nasty Deathclaws waiting inside of Deathclaw Sanctuary.

You'll find Vault 108 on the eastern edge of the world map. Head south from the Republic of Dave to reach it. Once you enter the vault, head to your left when you see the big blood stain, and pass the power generators. Head down the stairs into the lab area and you'll find the Charisma Bobblehead on a desk.

 Rivet City sits on the very southeast corner of the map, west of the Jefferson Memorial. You’ll find the Intelligence Bobblehead on a desk inside the Science Lab.

Head southwest from the Republic of Dave to reach the Greener Pastures Disposal Site. You’ll be exposed to lots of radiation while roaming through this area, so be sure pop some Rad-X pills beforehand.

The Arlington House is in the middle of the Arlington Cemetery. But to get there, you'll need to navigate the underground tunnel system. First, head into Marigold Station. Once you reach the first large room, jump down to the first floor on your left and take the left tunnel. Follow the Blue Line tracks and head through the door on your left when you reach the giant grates to exit at Falls Church. Head east till you reach the Falls Church/Arlington Metro Station. Once you reach the first large room, cut straight across the rubble and pass the Nuka-Cola machine.  Head east to discover Mama Dolce's. Then head north to enter the cemetary. The Arlington House lies between North Arlington and South Arlington. Head to the basement to find the Luck Bobblehead.

Above: You'll want to have at least six points in Luck for the Mysterious Stranger perk. It's the only way to get a Humphrey Bogart lookalike to randomly finish off your enemy when using V.A.T.S.
