This Seeking Tech guide will show you how to find the 4 Special Bots from Astro’s Playroom in Astro Bot.
For the first step, make sure you rescue these bots from Astro’s Playroom.
Afterwards, you need to open Astro Bot and then play through the Sky Garden level in order to unlock the Crash Site. You should also have at least two bots after beating this stage.
Once you get to the Crash Site, the four Special Bots should be found on the outer edges. To rescue them, press triangle when you get close to one in order to call in support. Afterwards, go towards the rock to help with the rescue. Do the same for the other three bots to unlock the rest.
