Hear Today, Gone Tomorrow/Double Whammy/Autopsy Turvy - S1-E13
Continuity mistake: Autopsy Turvy: When Flippy and Evil Flippy fly into the window of the music store, the door to the music store has its doorknob on the right side and its hinges on the left. A moment later, when the Mole is shown sweeping glass on the floor, the doorknob and hinges are now on the opposite sides. (00:18:03)
