- At the start of the episode, Michelangelo is on the couch reading comics, then standing next to Splinter moments later, then back on couch again.
- When Leonardo reads Dregg's billboard, he uses the words "officially" and "licensed", but those words aren't on the billboard.
- The positions of the hands on the clock Chronos plants in the Turtle Van change drastically between shots.
- The timer on Chronos' thermal bomb stays at 14 seconds for more than one second.
- When the Turtle Van arrives at the bridge, the lettering on the front of it is black instead of white.
- When the Turtle Van arrives at the bridge, Leonardo appears to be a lot bigger than Michelangelo.
- Right as Donatello breaks out of his ropes, Leonardo and Michelangelo have disappeared; they should be hanging next to Raphael like they are in an earlier shot.
