This scene in Taiwan went down because a Snorlax popped up, Pokémon Go's most rare non-evolved character. Thousands of people
with way too much time on their hands poured into the tiny streets of Beitou Park to catch Snorlax, a character that literally only eats and sleeps.
Scenes like this are how the zombie apocalypse is going to start. People think they're just playing a silly game, but then they step into a trap with a secret zombie-making substance in the air, leaving all those poor souls infected and screwing the rest of us out of a zombie-free future.
Zombies are going to take over, all because you wanted a Snorlax. You should be ashamed.
