Poke Eggs

Poke Eggs Pokemon eggs - thepokemonplace.com

Eggs can hatch Pokémon and also add XP and stardust to your arsenal. You can hatch them by walking around, so the more you play, the more you’ll gain.

And don’t think you can cheat by driving. The system only gives you credit for travelling under 20mph, so cycling and skateboarding are the only things you’ll get away with.
