Note: To get them, sadly you've to buy/unlock the" Nuka-Cola Collector Workshop" in the Creations Club first (You'll find the creation club in the main menue)

But for me it's worth, because beside a lot of cool stuff to furniture your homes and access to the "Nu Cafè Ola" you'll get also access to the 5 exclusive Bobbleheads

Quicktravel to the D.B. Technical Highscool. Enter the building and go straight to the downest level. Now your're in a room with a wooden bridge. On the end you'll find a table with the Bobblehead on it.

Just go to Fallon's Department Store. Go up to the highest level to the octagonal room. You'll find the Bobblehead on the table.

This is the easiest one. Just quicktravel to swans pond. Walk on the right side around the pond to the next building and you'll see a door to the "Prost Bar" in the sub. Enter the bar and walk to left room in the back. You'll find the Figure on a cabinet in the back.

Getting this one is actually a little bit tricky. It took some time for me to figure out the easiest path. So quicktravel to Greenetech Genetics. Enter the building, turn to the right and take the stairs to the first floor. Now look to the left and you'll see an elevator. Enter and activate it. When you leave the elevator head to the stairs on the opposite door in the room. Go 2 floors down and turn to an other staircase on the left of you. Now go one floor up and through the door on the right side. You'll find the Bobblehead on a desk, next to a broken computer.

For the last one you've to quicktravel to the Vault Tech Regional HQ. Head up the floors to Mr. Davidsons Office. The bobblehead is is next to his terminal.

Now you really deserved to own all five exclusive Bobbleheads - so place them wherever you want and have fun
