- In Mikey Gets Shellacne, Mikey's bedroom was on the right-hand side towards the back. But in The Invasion, Part 1, his bedroom was on the left-hand side judging from the direction of the Kraang gun fire shown in the hallway through his open door. In The Noxious Avenger, his bedroom is shown to be somewhere on the right-hand side again, judging from the direction Splinter leaves when he confiscates Mikey's TV. It is unknown if these are continuity errors or if Mikey actually moved his room at least twice over the course of the series.
