Steve Zaragoza, from the Cloverfeels Podcast, spotted a Slusho truck outside of Comic-Con last week, handing out free drinks. #InGame
The truck displayed a new twitter account - @SLUSHOTRUCK - and based on some of the tweets, it appears to be driving around the country.
There's also a snapchat snap code that gives you access to a special Slusho filter (for 1 hour).
I don't know much about Snapchat, but this appears to be some kind of secret message:
Wave for happy time robot?
The Slusho.jp website appears to be down at the moment (since no one uses flash anymore), so maybe some updates are coming?
