If you are replaying Astro’s Playroom to rescue the Special Bots that were added in the new updates, then you should make sure you grab the seven new artifacts.
You can find these in the claw machine in PlayStation Labo. You will need 700 coins in total to grab all of the gatchas in the machine.
The new artifacts are based on the PlayStation Slim, PlayStation Portal, PlayStation Access Controller, DualSense Edge as well as the PlayStation VR2 headset and controllers.
Once you unlock all of the new artifacts, take the portal to make your way down to the Secret Labo. You should then find the newly unlocked artifacts that you can play with.
