Ditto is now out in the wild in Pokemon Go! But it's a Pokemon who likes to disguise itself as other Pokemon... so how do you catch it?
Ditto won't appear on your map and it won't appear in your sightings radar. It'll be disguised as another Pokemon.
Commonly it disguises itself as a Rattata, Pidgey, Magikarp or Zubat.
Simply catch these Pokemon as you normally do, and when you've caught a Ditto a 'Oh?' will appear showing the Pokemon transforming in to a Ditto.
So it's time to start catching those Pidgeys again - you never know when one might be a Ditto!
Good luck finding your first Ditto!
