When you meet Cromdo in the desert, he will ask you to catch three Cheepoof for him to pay off a launchpad that he tricked you into using in the first place. Luckily for us, the launchpad is exactly what we need to catch these little creatures.
First, it is important to know that the Cheepoof only appears in the Scorched Gorge area between 6:00 AM and 4:00 PM. They also never land, so you will need to get creative to find them. Look at the rocks, and if you can see a Cheesy Patch, then you know that there is a Cheepoof nearby. Scan flying Bugsnax until you find one then set up the launchpad close to where it flies. Place your Snak Trap on the launchpad, then hit the L2 button and hold it to aim the launch pad at the Cheepoof.
Hit the R2 button to fire your Snak Trap at it, and hit R2 again when the Snak Trap is near it to catch the Bugsnax. You will need to be careful not to set it up near some of the more aggressive Bugsnax, as they will knock it over.
You should also wait to fire the Snak Trap at the Cheepoof until it is flying straight at you. The Snak Trap will just fly through the air, it won’t track the Cheepoof at all so you need time it well. After you catch three of them using this method, return to Cromdo and feed him the three Cheepoofs.
