Trivia[]

  • On April 29th, 2019, there were various reports of both forms of Shellos appearing around the world.[1] About ten minutes later, the spawns ceased and the Shellos were reverted back to event spawns.[2]
  • Both forms of Shellos appeared around the world in the first half hour. Then they were taken down and became region-exclusive Pokémon few hours later.[3]
