This page lists all of the available Treasure Pods in The Glass Desert.
While the Jetpack is not necessary to find some of these Pods, it is recommended to buy it to be able to reach a vast majority of them. Having fully upgraded Energy is also highly recommended, since some of these locations require extensive Jetpack usage to get to.
Additionally, there are no Green Treasure Pods in The Glass Desert, so the Treasure Cracker MK II is required to start opening them, however the Treasure Cracker MK III is recommended since almost all of them are purple pods.
