06NOTES & GOOFS

The Transport Modules appear for the first time since "The Big Rip-Off".
Even though Seymour is really a good guy persuaded to steal the Byndex-3 against his own wishes by Shredder, his toy lists him as a bad guy.
Vernon's talk show from "The Dimension X Story" is brought up again in this episode, mentioning that its ratings are suffering.
April's Turtlecom looks like the Turtles' version when she uses it to contact the Turtles as she is trapped on the sky tram.
Also how was April able activate her Turtlecom when her hands were tied up to the ropes of the sky tram?
When Donatello and Michelangelo hogtie Bebop, Donatello's "D" is white.
Seymour is animated mirror-flipped in parts of Act Two.
When the Transport Module burrows underground when Shredder and the mutants head for the space station, the mud splatter is the same color as the floor surface the Module was standing on.
Shredder is talking to Kraang on the Technodrome's display monitor at the beginning of the episode. His right hand and part of his clothing can be seen underneath the Technodrome's control panel after delivering his first line.
Right before Seymour turns himself into Michelangelo for the first time, one of the "n's" on the "Channel 6" sign is missing.
When the construction workers gang up on Leonardo and Raphael, Raphael is seen with Leonardo's colors.
When the turtles find April trapped on the sky tram, they arrive with Raphael on the very far right next to Leonardo. But in the next shot, Leonardo is suddenly on the far right next to Raphael.
