One crucial challenge is the difficulty in locating Sour Sandwich Pokémon, as they are scarce and dispersed. To overcome this, players can utilize online resources and coordinate with other trainers to enhance their chances of encountering these elusive creatures. Moreover, exploring various habitats and using specific lures can increase the likelihood of encountering Sour Sandwich Pokémon.

Another significant obstacle is the limited availability of Sour Sandwich Pokémon during specific times. To address this issue, players should plan their expeditions strategically, concentrating on periods when these Pokémon are most likely to spawn. Additionally, staying updated with game events, following official announcements, and joining online communities can provide valuable information about upcoming Sour Sandwich Pokémon appearances, allowing players to adjust their schedules accordingly.
