Smiling Friends is currently in the works on coming back to Adult Swim with Season 2 some time later this year, and Adult Swim has brought the series back early with a fun new promo! Smiling Friends had one of the most standout original animated series debuts with Adult Swim in the last few years. The first season surprisingly premiered within a single night, and ended up being such a success with the network that Adult Swim had announced that Smiling Friends would be returning for Season 2. Unfortunately, it's just been a while since we've gotten to see it in action.
