If you've jumped on the Pokemon GO app recently you may see a new event.
The Sinnoh Collection Challenge involves collecting a handful of Pokemon.
Two of those happen to shadow Pokemon, Stunky and Snover.
Here's everything you need to know to catch them both!
Sinnoh Collection Challenge Shadow Pokemon
The only way to get these Pokemon is by beating Team GO Rocket.
Don't worry it's not too tall of a task.
You'll need to find grunts at PokeStops or flying in a hot air balloon and defeat them.

When this timer runs out they will be returned back to normal.
