WATCH OUT: Pokemon Are Fighting Back!

Pokemon are tired of being caught, and they’re starting to fight back.

That’s the concept behind a new video created to promote tourism in the Swiss city of Basel.

Watch as a gang of Pikachu turn the tables on Pokemon Go players and attack them with an oversized Pokeball in “Pokemon Go The Revenge.”

While it appears that some of the incidents are staged, the segment is so funny that it’s going viral in a big way, with more than 50 million views on Facebook.

“We were hoping it would go viral, but the result is just incredible,” Christine Waelti, manager of marketing and communications at Basel Tourismus, told AdWeek. “It’s every marketer’s dream come true.”

The tourism agency also added a guide to the city’s website showing places to catch Pokemon, along with notes about which monsters have been found in certain areas. Just be careful out there. You never know when one of them is going to try to catch you instead.
