The twitter user, if his handle didn't give it away, is one of the writers for the show. Actually based some of the locations visited in the episode off places he himself visited. https://twitter.com/AlanTheWriter/status/876522907454668800

Basically Sonic, Tails, and Knuckles take a road trip to get to a concert for their band of sorts but shenanigans happen along the way. It's actually really good, the moment in question happens around the 4:09 mark.
