Community Day raises the spawn rate for a special event Pokémon -- this time around it's Bulbasaur -- and gives you a special move for its third-tier evolution. Community Day is on Sunday, March 25, which is a slight change from the past two, which were on Saturdays. Note this is for catches only, so don't spend Community Day hunkered at home evolving. A little caution this time around, however: I'd be surprised if this Community Day will be nearly as popular as last month's, which offered the valuable Dratini in both regular and Shiny variants. Not only does Dratini evolve into Dragonair and Dragonite, the last of which is one of the most useful Pokémon in the game, the catches also count towards the rare Dragon Tamer medal.
