Yache Berry in Cobblemon.
Yache berries in Cobblemon grow best in freezing and taiga 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.
Dragonite (10%), Jumpluff (10%), and Flygon (10%) and 26 other Pokémon drop Yache Berries when defeated; plant one and its favourite mulch, Coarse Mulch, gives the best harvest.
Growing Yache Berries
Freezing: deep frozen ocean, frozen ocean, frozen peaks, frozen river, grove, ice spikes, jagged peaks, and snowy beach and 3 more. Taiga: grove, taiga, and snowy taiga. Plant in one of these for the growth bonus; the berry still grows elsewhere, only slower.
