Continuity mistake: After the Decepticons dig up Skyfire they look at his memory banks to show what happened to him. In the flashback it shows Starscream transforming into his Earth jet mode which he shouldn't have had because it takes place before they all crashed on Earth.
Continuity mistake: Optimus Prime, whose primary color is red, when being tied to a rock alongside his troops during the episode's climax, turns blue for a second.
Continuity mistake: Skyfire's Decepticon symbol changes color throughout the episode. Sometimes it is purple and sometimes it is red.
Answer: These two were 'dinosaur' cassettes Overkill and Slugfest, then-new toys. They turn up this once and that's it, though.
