Today’s the first day of the latest Pokemon Go Fest that takes place in Dortmund, Germany. The event kicked off today and continues until July 7. Participants at the event could be in for an exhilarating treat, too.

The German Pokemon Go Twitter page released a tweet hinting at the potential for players at the Dortmund event to take part in Team Rocket battles. Check out the tweet we’re talking about, and look closely at the background of the image.

Do you see it?

In the background, there’s a distinctly dark balloon floating in the sky a reasonable distance out from the pair of trainers in the center of the photo. Upon further inspection, you’re going to notice a red outline painted across the black balloon.

Fans of Pokemon would instantly recognize this as the iconic Team Rocket balloon featured throughout the anime. Team Rocket would use it travel, and they’d fly away on it when the heroes bested them at the end of the show.

There are no official details about any Team Rocket battles, at this time. They could happen later on in the event, and when they do, participants had best prepare themselves to step in and foil whatever plans the evildoers are up to in Dortmund.

We also don’t know if those who are not attending the Pokemon Go Fest in Dortmund are going to have the opportunity to get in on the exciting action.

We’ll find out more details in the future. For now, trainers at Pokemon Go Fest Dortmund, keep your eyes out for that iconic dark balloon and be on the lookout for any talking meowths.
