Petrichor: Cows is the final expansion for Petrichor. Cow meeples are now strolling among the crops, releasing Manure and Methane gas! The expansion adds cute cows to the mix, bringing with it a new Graze Action that allows players to affect the world's climate, a Climate Board and a whole new set of Climate Sensitive Trees. The Cows Expansion is compatible with both the Honeybee and Flowers expansions and supports both 5 player mode and the Southern Winds solo mode.
