This is the first episode to air on BBC1 in the UK, due to the BBC deeming Season 1 too violent to be aired. This season and the next are the only seasons ever aired on a BBC network during the show's nine-year run.
Vernon Fenwick's voice actor changes from Pat Fraley to Peter Renaday starting with this episode. This was done to even out the number of roles each actor had to deal with; otherwise, Fraley would have had three regular characters (Krang, Baxter Stockman and Vernon) and Renaday would only have had one (Splinter).
Baxter Stockman's first appearance since the episode A Thing About Rats (1987), having been committed to an asylum. He now has longer hair.
From this episode onward, Rocksteady no longer wears his helmet.
The animation has been redesigned to have a higher quality, from the design of the characters to the background settings.
