This Seeking Tech guide will explain how you can unlock the Breezy Rescue trophy in Astro Bot.
Use the following video as a reference:
For the first step, you should make sure you have the latest patch downloaded. You then need to beat the main campaign in order to unlock the Stellar Speedway galaxy.
You should then be able to go to the Helium Heights stage from there.
To get this trophy, you need to beat the blue bird to the stage exit.
In order to inflate and float, you only need to press R2. To deflate quickly to make a landing, you need to hold down R2. If you can’t tell where you are landing, then you can use your shadow as an indicator.
If you follow these mechanics, then you should be able to outrace the blue bird.
