The 24 hour live-stream
of the Glimwood Tangle forest has ended and it has revealed a new Pokémon! The stream was very sparse with Pokémon popping up on average only every 30 minutes or so. As the stream went on fleeting glimpses of something new were seen, but often obscured by something else like Impidimp walking through the shot.
Finally we got a good glimpse of a pony Pokémon that looks similar to Ponyta and has the same cry. Nothing has been fully confirmed yet but it's presumed to be Galarian Ponyta.
