Occa Berry in Cobblemon.
Occa berries in Cobblemon grow best in jungle, sandy, thermal, and volcanic biomes, take 45 to 55 minutes to fully grow, and yield 1 to 3 berries per harvest; they work as a general cooking ingredient in the campfire pot.
Forretress (5%), Mawile (5%), and Wormadam (5%) and 14 other Pokémon drop Occa Berries when defeated; plant one and its favourite mulch, Humid Mulch and Sandy Mulch, gives the best harvest.
