Bricksburg, The Old West, and Cloud Cuckoo Land all have 3 Instruction Pages hidden throughout the world. Finding these will allow a Construction character to build at the platform in the world. This will also result in unlocking a Red Brick. These Instruction Pages cannot all be found at the start of the game, as some are hidden in spots that only certain characters can unveil. These characters are progressively unlocked while playing through the main story. The first and easiest Instruction Page to find is in the construction site. After entering through the gate, go to the left and there you will hear a character saying he forgot his drill. Near him there is a marking on the floor denoting that it can be broken with a drill. Use a Construction character to drill through the marking on the floor. The Instruction Page will be in the hole. The second Instruction Page can be found near Emmet's home. Facing Emmet's house, look at the right side of the town square. You will see a pink fence.
Break this fence and use it to build a surface for a female character to climb. Wall jump up to the roof. Here you can flip a switch and open a door so male characters can come up as well. (While up here you can also break the bench and rebuild the billboard, another side mission in Bricksburg. Also behind the fence on the right, there is a cat that needs to be returned to Mrs. Scratchen-Post). Jump down onto the yellow and white overhang. Then have Vitruvius throw his staff into the hole on the building to the left so a female character and jump across and grab on and make her way to a balcony. The Instruction Page will be there. The third Instruction Page can be found inside a restaurant near the ice cream truck. This cannot be accessed until either President Business or Lord Business is unlocked. Once either of them is, switch to this character and walk over near the construction site gate. Do not enter, but look to the right. You will need to destroy the dumpster by the camera post to build a platform, then use it to make President/Lord Business taller.
Once you have done this, walk back over to the restaurant and look to the right. There will be a large tree and on the ground there will be a marker. Walk over to it and press Circle/B to activate the switch. This will open the doors in the restaurant, allowing you to walk inside and grab the Instruction Page. (There is also a cat found here, which is needed for Mrs. Scratchen-Post's sidemission). The first Instruction Page is found near an aggressive horse found on the right as soon as you enter The Old West. Vitruvius is needed in order to get this, as other players see the horse and refuse to approach it. The Instruction Page is in the middle of the fenced area. The next Instruction Page is on the roof of the saloon. To get up there you will need a female character. Upon entering The Old West, go straight up to a building, that is the saloon. Then, head towards the building on the left. Climb the netting to get onto the balcony. Walk to the other side then jump and grab hold of the bar to work your way up to the roof.
From here, follow the coins and jump across the roof to the building straight ahead. Keep following the coins and jump to the building on the right. Here you will see a structure. Destroy this structure and walk into the rubble, the Instruction Page will be there. (Once up there you might as well continue to explore the building as a one of the Gold Thieves is hiding out in the building). The last Instruction Page in this world cannot be found until you unlock a character that can fire lasers, like Bad Cop or Superman. With an appropiate character, head towards the saloon. Then walk over to the right and you will see the sheriff's building. Next to it is a gold jail cell. Use a laser on the jail cell and knock down the door. Inside is the third Instruction Page. The first Instruction Page is hidden inside a building in the upper left part of the main cloud. Once you enter Cloud Cuckoo Land, head straight and slightly left. You will see a target on the second floor of the building between the silver door and rainbow stairs.
Throw something at this target to break the wall. Then, as a female character, use the bar to get up to the hole and collect the Instruction Page. The second Instruction Page is found through the silver door on the left. Using a character with explosives, destroy the door and head forward. On the first cloud, use a Master Builder on the green circle to put together a stair case. With a female character, walk up the stairs and across the tight rope and the Instruction Page will be in the middle of the room. If you have a character with flying abilities, you can also just fly directly up there and collect the Instruction Page. (A Red Brick can also be found here right next to the Instruction Page). The last Instruction Page requires a character that can shoot lasers. Upon entering Cloud Cuckoo Land, head up and towards the right until you see a gold door. Destroy it and proceed forward. Once you get to the next cloud, look at the tower. There is a hook for a character like Batman to latch onto and pull the tower down.
Then, you will need a female character to jump up and into the tower. The Instruction Page a clearly visible in the middle of the room. Alternatively, if you have a character with flying abilities unlocked you can just fly to the top of the tower and collect the Instruction Page. (Up here there is also a Uni-Kitty In A Box to be found which can be opened by a Construction worker). This side mission is available after buying the Mrs. Scratchen-Post character. To begin the mission after buying her, walk up to her then press Circle/B to interact with her. Now you must find the five cats located throughout Bricksburg (Note: You may have found some will exploring before, but now after accepting the mission they will follow you back to Mrs. Scratchen-Post). After completing this side mission the player will be rewarded with a Red Brick. The cats do not need to be found any particular order. The first cat can be easily found very close to Mrs. Scratchen-Post. Using a character with a grappling hook like Batman, walk directly to the left.
You will see a red bench. Destroy it and use it to build a latch on the balcony above you. Pull the balcony down and a cat will fall down. Walk back to Mrs. Scratchen-Post and the cat will follow you. The second cat can be found not too far from Mrs. Scratchen-Post. Head over to the right side of the town square. Here you will find a pink fence post that you need to destroy. Once destroyed, use it to build a surface on which a female character can jump up off and onto the roof. (If you have already found the Instruction Page or Billboard up here, this will already be done. The door to get up there however, needs to be re-opened every time the world is loaded). Once on the roof, head to the right and use the bar to get to the other side of the fence. Here you will find the cat. Simply jump down and return to Mrs. Scratchen-Post and the cat jump down with you. To find the third cat, you need to have a Space character, such as Benny. Using this character, walk to the restaurant by the ice cream truck.
Walk all the way up all the stairs. Then, walk all the way to the left and you will see a computer. (From this floor, you can use a female character to cimb the netting on the right and reach a Billboard). Hack the computer and a cutscene will initate in which a cat walks off a train. Take the cat back to Mrs. Scratchen-Post. This cat requires Uni-Kitty to be unlocked. Using Uni-Kitty, walk over to the police station. Destroy the rainbow bricks and build a catapult. Now with a character that can throw an object, use the catapult. It will shoot you up onto a roof with a porta potty. Hit the target above the door and a cat will walk out. Return the cat to Mrs. Scratchen-Post. This will likely be the last cat you get as it requires President or Lord Business. Using this one of these characters, walk over to the construction site entrance, but do not enter, instead look to the right. Underneath a surviellence camera there will be a dumpster. Destroy it and build a platform, then use it to make President/Lord Business taller (The platform will already be there if you have done this to get the Instruction Page).
