To get this achievement, you have to "inspect" (with
) all the
9 posters
in one playthrough.
№1: Paper WhaleIs found in the train right at the beginning when you play "Simon says" with Finn. It's on your left.
№2: FinnIs found shortly after, where you meet your masked grandparents for the first time. It's on your left.
№3: GaspImmediately after you finished the "puzzle" with your grandparents (immediately after poster 3) in the train in the middle of the room with all of the masked people. Again, on your left handside.
№4: Run Finn, RunIn the train, before you get to the treehouse for the first time. Finn starts disappearing all the time (vanished into butterflies). Finn vanishes on your left, the poster is on your right handside.
№5: HushAfter the first time in the treehouse, when your are back again in the train and Finn is mad at you. First you have to open the closed door with the key and then you will find yourself again surrounded with people with masks on. The poster is in this compartement on the far left (behind your mother).
№6: ForgottenAfter you assembled the characters correctly (location of Poster 5), you will come into a compartement where you meet the masked people again, this time in the correct positions. The poster is on the left, near your boyfriend and granddad.
№7: The Storm and Revelation This is found in the part where Finn sets things in the train on fire. Immediately after you extinguished the fire, you can find the poster in this compartement on your left.
№8: Rabbit BoyThis is found when you find yourself on the island and you get to the part where you enter the cave. In the sinister tree house the poster is hanging on the back wall of the house (in front of the camera, which you can pick up for an achievement).
№9: 11 RabbitsThe last poster is found immediately after the last one. When you have destroyed the umbra (by pulling it ino the light), you will descend the ladder again into the now very dark train. The poster is hanging behind the tree on your left.
There is a very good YT-Guide with all the rabbits, too. Check the guide from
