Shiny Pokemon

Shiny Tentacool and Tentacruel are making their debut in Pokemon GO! As with most event related shiny Pokemon, we don’t expect their shiny odds will be boosted. However, there’s always a chance Niantic will increase Tentacool spawns and make shiny hunting easier.

Shiny Tentacool and Tentacruel


  • Complete as many Trainer Battles as you can. At the very least, do three daily battles. Increased Stardust + a Star Piece can give up to 3000 Stardust per day.
  • Don’t forget to use your free Raid Pass! Charged TMs are a valuable item, especially with GO Battle League coming 2020. We suggest trying on viable T3 solo raids and having some fun while farming Charged TMs.
  • Stock up on Revives at PokeStops.
  • There could be great Pokemon hidden in event specific Field Research. We will update this page with Supereffective Week Field Research tasks as soon as they’re known.
