Lures are the key to these new evolutions.

Glaceon, Leafeon, Magnezone and many more Pokemon from Sinnoh are coming to Pokemon GO with a new update.

This is possible through a new lure mechanic that acts like the Mossy and Icy Rocks within the mainline games. Here is the full announcement below.

Trainers,

We’re excited to announce that more Pokémon originally discovered in the Sinnoh region are coming to Pokémon GO! From seas and beaches to mountains and beyond, be on the lookout for Cherubi, Gible, Hippopotas, and others. We hope you’ll enjoy the fun and surprises as you encounter these Pokémon in the wild and hatch them from Eggs. Also arriving in Pokémon GO is a powerful Ground-type move—Earth Power!

Plus, we have more exciting news to share. Thanks to your dedication in helping Professor Willow with his research, he has made some amazing improvements to our favorite module—the Lure Module. Inspired by research collected from around the world, three upgraded Lure Modules have been developed. These modules attract Pokémon in the surrounding area while creating a temporary special habitat. Soon you’ll be able to harness the power of Glacial Lure Modules, Mossy Lure Modules, and Magnetic Lure Modules. These lures might even have the potential to cause Evolution in certain Pokémon!

More details on these exciting additions:

• Additional Sinnoh Pokémon are now available to catch in the wild and hatch from Eggs.
• Earth Power is a powerful Ground-type Charged Attack that could lower your opponent’s defense in Trainer Battles.
  • Certain Pokémon recently arrived from the Sinnoh region will know Earth Power.
  • Other Pokémon that could know Earth Power include Nidoqueen, Nidoking, Aerodactyl, Camerupt, and Claydol.
• Glacial Lure Modules, Mossy Lure Modules, and Magnetic Lure Modules can be obtained in the in-game shop and will be available later this season as rewards for completing new Special Research tasks.
• These Lure Modules attract local Pokémon as well as bonus Pokémon based on the type of lure.
  • Glacial Lure Modules attract certain Pokémon that love the cold, such as Water- and Ice-Type Pokémon.
  • Mossy Lure Modules attract certain Pokémon that love to frolic among the leaves, such as Bug-, Grass-, and Poison-Type Pokémon.
  • Magnetic Lure Modules attract certain Pokémon that are drawn to electromagnetic forces, such as some Electric-, Steel-, and Rock-type Pokémon.
• When Trainers are within range of a PokéStop with an active lure of the appropriate type, and they can successfully spin its Photo Disc, Evolution of Magneton and Nosepass will be enabled, as well as certain Evolutions of Eevee.
  • You can choose whether or not to proceed with these special Evolutions on the Pokémon’s detail screen.

What other surprises will you discover? The only way to find out is to get out and GO!
