CPU Plaza puzzle piece 1 location in Astro's Playroom explained
The first CPU Plaza puzzle in Astro's Playroom is located on the lower level of this area, which can be reached by going down the right-hand side of the plaza.
Once in this area, you'll want to go to the far-left hand corner from the bottom of the ramp, you'll find three sets of wires that you can pull out.
Pull each one out until the puzzle piece is revealed.
CPU Plaza puzzle piece 2 location in Astro's Playroom explained
The second CPU Plaza puzzle piece in Astro's Playroom is located on the second section of platforms that you activate.
To collect this piece, you must first pull out of the wires that can be found atop the ramp on the left-hand side of the plaza.
Next, you need to climb up the platforms that have appeared out of the side of the wall, until you reach another set of wires; pull these to create more platforms for you to climb.
Now, you'll want to jump over to the platform on your left, which will lower depending on which end you stand.
You'll want to ensure that you're standing on the end nearest the platform you just jumped from. The platform is as low as it can go, quickly run and jump to the end, so that you can reach the bounce pad.
Finally, all you have to do is use the jump pad to jump left-wards to reach the puzzle piece.
CPU Plaza puzzle piece 3 location in Astro's Playroom explained
The third CPU Plaza puzzle piece can be found once you've activated the platforms on the right side of the plaza.
To do this, you must first climb to the top of the platforms on the left-hand side of the plaza, pulling out the wires you find there to create a line between the two platforms.
Slide down this line and then pull out the next set of wires to activate the new set of platforms, including the one with the puzzle piece.
To reach the puzzle piece, you'll first want to climb atop the lowest moving block.
From there, you can jump across to the moving block on your left and, on this block, you'll want to wait till it's moved upwards.
Now you must wait again, until the large moving platform to your left comes into view and, once it does, you can easily jump across to it.
You'll want to stay on the right-hand side of this platform, so that you can easily jump atop the next block and avoid being knocked off by it, as this block overlaps with the platform. When it does so, however, you can easily jump onto it and let it carry you to the third puzzle piece.
CPU Plaza puzzle piece 4 location in Astro's Playroom explained
The fourth and final puzzle piece in CPU Plaza in Astro's Playroom is located at the top of the platforms that you can activate for the right-hand side of the room.
To reach it, you must first pull the second set of wires that can be found on the left-hand side of the room near the third puzzle piece.
Now you just need to navigate your way up the wall, which will include multiple moving blocks and a power button, which will activate the jump pads that will allow you to reach the final platform.
If you're having problems navigating this area, we suggest heading to the top of the left-hand side of the platforms, where you'll get a good look at the opposite wall and the rhythm of the moving platforms.
Once you reach the final platform, all you have to do is walk to the end and jump to collect the final puzzle piece.
If you want to collect the puzzle piece again, you can always open up the map screen by pressing the Options button and restart the CPU Plaza level.
