For being a small pack-in game included in the PlayStation 5, Astro’s Playroom hosts quite a bit of content to enjoy for multiple hours. There are four levels throughout the game’s four worlds, each with a collection of references and collectibles looking back on the PlayStation brand. If you find the four puzzle pieces in each section, you will notice the walls of PlayStation Labo being filled in with a colorful mural to each generation of PlayStation consoles.
However, even if you grab all of the pieces from those worlds, you will not finish the murals. You will need to grab the ones in the hub world as well. Here is where to get the puzzle pieces in CPU Plaza and PlayStation Labo.
There are four puzzle pieces in the CPU Plaza. This room allows you to choose which world you want to go into. You can find one by entering the basement on the right upon entry. Go down the slope and turn left to find a platform with three bots and wires for you to pull. Pull the three wires and the puzzle piece will appear.
Go back to the main floor and start climbing the wall on the left side from the main entry. Once you reach a platform that rotates when you stand on it, angle it so you can jump on the bounce pad to the left. It will launch you into the second puzzle piece.
From the previous piece, use the platform to move to the right and up. Keep climbing until you find a wire you can slide across to the other side of the room. Climb up a couple of moving platforms and make your way to the left for the third puzzle piece.
When you have that piece, make your way to the right and continue climbing. Eventually, you will hit orange bounce pads that will bring you to the final puzzle piece. Be careful, though; it is on top of a narrow path, and if you fall, you will need to climb the entire thing again.
The puzzle pieces in this collectible room are all relegated to the gacha machine. When you enter the room, straight ahead will be a giant red button and four robots standing near it. If they are holding boxes, punch them, and each will give you 100 coins. Jump on the red button and you will open the gacha machine. Each pull costs 100 coins, and you can get the aforementioned puzzle pieces, artifacts, statues, or cans to crush. Hold L2 to pull the level and R2 to open each capsule.
