Other mistake: The battle droids - including the commando droids featured here - habitually have two broad fingers and a thumb. So how can a commando droid squeeze itself completely into clone trooper armor without its broad fingers tearing open the gloves, since it can't separate its fingers?
Land of Hold/Penny Henny - S2-E17
Deliberate mistake: When Garfield brings Jon to the broken TV, the scene's animation is still unrendered. (00:01:04)
Bat Mitzvah Crashers/Super Secret Weakness - S1-E5
Continuity mistake: In "Li'l Orphan Happy" when Ben makes his mom the tuna salad, it has lettuce around it, but in the close-up the lettuce disappears. When it gets zoomed-out on, the lettuce is back.
Triumvirate of Terror! - S3-E8
Continuity mistake: Cheetah slams Superman into what looks like a computer mainframe. He stumbles forward and falls to his knees. The next shot as Cheetah kicks him, he is suddenly standing again and in the middle of the room, away from the mainframe. (00:12:55)
Iron Forged in Fire: Part One - S1-E1
Continuity mistake: As Rhodey and Tony are walking by a building, Rhodey tells Tony to not worry, as in two years he can fire Stane. The first view shows their shadows directly under them, like the sun is at its zenith. It then cuts to a shot from above their heads and now their shadows are elongated and cast on the wall beside them. (00:09:35)
Audio problem: When Blob is approaching the police car with Toad inside, the sound of his heavy footsteps is not in sync with his stride. (00:01:30)
