A Day in the Life of Retsuko - S1-E1
Continuity mistake: After Ton bashes Retsuko for not getting her tea right, she sings some death metal in the bathroom before joining Fenneko back at the computers and they start talking. Between them is a pink cup with some orange scissors, and an assortment of writing utensils. They are fanned out, but show that the red one is closed to Retsuko with the black in the middle and the yellow closer to Fenneko. When the camera changes angles to show them both sitting there, this order of pens is flipped, with the scissors still being in the same spot.
Continuity mistake: After Cat Burglar steals Craig's staff at the award ceremony Silver Fist goes after Cat Burglar, and just as Silver Fist climbs up on the roof, his crossed straps become crossed the opposite way, mid shot. (00:05:50)
Continuity mistake: Just before the portal opens where Sonic comes out by a water fall, you get a good view of the ground around where he comes out at and there are no holes. But once he emerges, he looks around and then looks down and suddenly there are large holes that become what he focuses on. (00:00:25)
