Rumble in the Big House - S2-E9
Factual error: During the final confrontation, Xiao Fung keeps blowing and blowing, and Valmont/Shendu, Finn and Ratso are blown through the tunnel and right into the middle of a garbage dump. But they have to break through a layer of garbage in the process, and since Xiao Fung's breath keeps blowing, there should have been a hole through which his windy breath would pass, instead of an intact layer of refuse.
