Audio problem: In the scene where Kim is running across grass-covered Japan to stop Duff Killigan, when she talks her lips don't move along to the words.
Pompeii and Circumstance - S1-E12
Audio problem: When Daphne takes off in the golf cart after picking up the rest of the gang, it makes the sound of tires on pavement. But they are on the dirt floor of the Coliseum. (00:08:55)
Audio problem: In the episode where the Wheezers obtain super powers, at the end of the episode, they are all singing their "Sitting and Singing" song surrounding the flaming duck. When the camera cuts to Carl putting his glasses on, the song can still be heard, but everyone's mouth just keeps saying "Standing, and standing, and standing," even though there are more words heard than just that.
