In a last ditch effort to get you to open up Pokémon Go for the first time since July, Niantic is adding the mother-of-all gimmick: Ditto.

Ditto is the only blob like Pokémon not included in the original Series 1 lineup of Pokémon Go — and this creature is blessed with the gift of Transform, the ability to mimic other creatures it sees.

Ditto, which has the ability to take on the form and abilities of the other Pokémon it’s facing in battle, is finally available for players to catch. Players have started reporting that they noticed Ditto after catching normal, low-level Pokémon like Zubat, Pidgey and Rattata. Upon being caught, the Pokémon transformed into Ditto.

From photos that players have been posting, it appears that the Dittos being caught retain pretty high CP. The Pokémon is available to catch in every region, based on reports, with players from Sweden, Australia and the United States posting images of the Dittos they’ve caught.

And that’s exactly what Ditto does in the game: hide under the guise of other Pokémon. In order to catch Ditto, you may have to catch a bunch of other scrub Pokémon to find the real deal — even the Pidgeys and Rattatas. How else was Niantic gonna make sure you kept walking around and playing? Sneaky, sneaky.

Once you have Ditto, you can take it to battle at the gym, where it can transform itself to copy the first Pokémon (look, IVs, stats & all) it sees and retain all the moves for the remainder of the fight. If it sees another Ditto, however, things stay the same and you’ll just have to aggressively tap your way to defeating the opponent — the ironic Struggle to defeat.

If your family is anything like mine, they’ll be pretty convinced Pokémon Go is still very much a thing and won’t question much if you decide you’ve had enough Thanksgiving and need to go for a Ditto hunt. At least that’ll be my excuse to step out of the room.

The last non-legendary Pokémon from the original 151 to make an appearance in Pokémon Go, Ditto, has finally been included in the game.
