When you first come into Nibelhiem, talk to the boy on the east side of the town. He will tell you that there are Seven Wonders you can help him solve. Note: Do not go to the Mako Reactor with Sephiroth until the first two are completed.

First Wonder: Inspect the water tower to solve the Wonder of the town's red water supply. You will get the Phoenix Summon here.

Second Wonder: Inspect the painting of the girl in the guest room in the inn. Go back to the boy, then back to the painting. Walk downstairs to see if the innkeeper walks upstairs. If not, inspect the painting again. Slowly follow him without passing him or starting the scene with Sephiroth.

Third Wonder: When escorting Cloud and Tifa back to town, talk to each child in the intersection with the Mako Fountain. Take the path behind the children all the way to the end to encounter the "Wonder" bombs. Destroy all three of them before they explode by hitting them as they expand to make them shrink again. Once you defeat them, go back to the village and exchange the Gold Shard you received for defeating them for a Safety Bit.

Fourth Wonder: This Wonder is in the Shinra Manor about a laughing safe. Go to the northwest room on the second floor to find a piece of paper and the safe, which contains clues on how to open the safe.

First digit: Knowledge overflowing. Count the number of books not on the bookshelf in the room on the east side by looking through the keyhole. Count the books on the floor and on top of the book shelf.

Second digit: Unwelcome faces. Count the number of Dorky Faces in the east room on the first floor. They disappear and reappear but in the same places.

Third digit: Tasty reminders of home. Count the number of Dumbapple and/or cans in the room on the second floor in the back of the west wing. Also look for them behind or under furniture.

Fourth digit: Resting on all four feet. Count the number of chairs in the west room of the first floor.

Go back to the room, and put in the deciphered code, and find a Cactuar in the safe and the Vital Slash Materia. Return to the boy in town to find out about the Fifth Wonder.

Fifth Wonder: The boy speaks of bloodcurdling moans in the caverns of the Shinra Manor. Go to the caverns, and defeat four Sahagins. Go into the rooms on the side of the cavern, and unlock each coffin until you find a man in the coffin, who is none other than Vincent.

Sixth Wonder: Note: You must do the preceding five Wonders first. While in Nibelhiem when Sephiroth has set the town on fire, there is a boy standing near the store. He says that his mother is trapped inside and you have 1:00 to get her out. Unfortunately there is too much smoke to see, so you must blindly guide Zack through the building. First, guide him to the far right of the store, then toward the rear, then left, next to the front, and finally to the right. Press X when prompted, and lead Zack back through the same route and out the front door. The boy will give you an ATK Up++.

Seventh Wonder: Note: You must do all preceding Wonders first. The boy will send you a message in the Outskirts of Nibelhiem in the following chapter about the state of the village and the lack of a Seventh Wonder. He has left a treasure as a thank you for rescuing his mother somewhere in the village, if Zack can find it. Go past the save point toward the farmhouse in the Nibelhiem Outskirts, and look on the ground near the fence for a glowing red object. It is the Wall materia, which is the Seventh Wonder.
