Pokémon Go features all 251 from the first two generations, and just like the main games, some are more elusive than others.
Tauros, Kangaskhan, Mr. Mime and Farfetch'd - as well as Gen 2's Heracross and Corsola - are some of the Pokémon in question, which are all region-locked to specific locations.
While all of them make an Pokémon make an appearance in datamining efforts - which also uncovered a great deal more about Pokémon Go's hidden mechanics - the lack of actual encounters with these Pokémon in the wild make them among the rarest in Pokémon Go.
Over a year after release and creatures remained locked to their specific regions. If anything, the issue had grown in complexity, with newcomers Heracross and Corsola having their own exclusive locations of their own - the latter across continents.
There is, however, hope in sight for those who can't jump on a plane - upcoming Safari Zone events in Europe are set to see these region-exclusive creatures make their debut in other regions, albeit almost certainly temporarily.
How to catch Tauros, Kangaskhan, Mr. Mime, Farfetch'd, Heracross and Corsola in Pokémon Go
We've put together a table below with everything we know on the region exclusive Pokémon, including where abouts within their respective regions you can hope to catch one.
|Tauros||North America||Normal||Generally everywhere, some reports of it appearing in expansive, desert-like or rodeo-related areas||The general word is that this includes all of North America, but whether or not it appears in South American countries is still up for debate.|
|Kangaskhan||Australasia||Normal||Generally everywhere, with reports indicating it's appearing in cities and parks in particular||There's some debate here over whether Kangaskhan is exclusive to just Australia, or Australasia as a whole, with some differing anecdotal chatter from people in New Zealand.|
|Mr. Mime||Europe||Psychic/Fairy||Generally everywhere, including city centres like London||Yes, the UK still counts as being in Europe; we voted out of the EU, not the continent.|
|Farfetch'd||Asia||Normal/Flying||Generally everywhere, being a normal type. Reports of Farfetch'd appearing in city centres and parks in particular, likely due to its part Flying typing.||Japan and South Korea seem to be particularly abundant places. There are some pretty large numbers of people reporting Farfetch'd appearing en masse in Japan since their servers went live.|
|Heracross||Latin America, south Florida and Texas||Bug / Fighting||Generally everywhere.||Though it's described as Latin America region exclusive, many reports of southern parts of Florida and Texas have also reported sightings.|
|Corsola||Tropics||Psychic/Fairy||More common in water areas between the two Tropics.||Early research suggests between 31N and 26S. In short this includes - but not all parts of - south Florida, Latin America, Africa, Asia and Australia and more.|
The 2014 Pokémon World Championships Masters Champion, Sejun Park, shared his experience catching Farfetch'd in South Korea:

Can the region exclusive Tauros, Kangaskhan, Mr. Mime, Farfetch'd, Heracross and Corsola be hatched?
No, you cannot get any of these creatures through walking and hatching Eggs. Information at launch suggested as such - and as with regional data in general, Niantic has been remarkably opaque in their explanation of Pokémon Go's mechanics so far - but that reliance on users reporting their experiences online, it's understood there's no way to get them in this way.
So, the only way to get the above is to be physically in those regions and catch them in person, which is an expensive pursuit unless you holiday or travel for work across the globe. That is until trading arrives, which has yet to be dated or discussed beyond an interview following the game's initial release.
