A new event is coming to Pokémon Go, the Cozy Companions event, set to kick off on August 6th and run through August 12th. The main attraction of this event is the debut of two Pokémon from the Galar region: Snom and Frosmoth. Snom will only appear in 7 km Eggs, requiring players to hatch a large number of eggs to obtain it.
To evolve Snom into Frosmoth, players must complete several requirements, including earning 400 Candies and 10 Hearts with Snom as their Buddy, all under nighttime conditions. This steep evolution requirement is seen by some players as an “egg wall,” which can be frustrating due to the reliance on luck when hatching eggs.
The event also features other Pokémon from the Galar region in eggs, but fans of Egg Hatches are likely to see this as a tactic to sell Super Incubators. However, not all players share this sentiment, and some enjoy the challenge and longer completion times that come with these events.
