This is the last Jimmy Neutron/Fairly Odd parents Crossover and Jimmy Timmy Power Hour Episode ever
According to Butch Hartman's blog, this was produced as the final episode produced for both the Fairly Odd Parents, and Jimmy Neutron. However Nick would eventually choose to revive the Fairly Odd Parents for a 6th season two years later.
To date, this was the last Fairly OddParents project for former head writer/producer Steve Marmel, who was also responsible for the franchise's many supporting characters. (Marmel left over disagreements with series creator Butch Hartman on this and Hartman's other series, Danny Phantom (2003), which he also worked on. This may explain why many of the supporting characters, including Chester McBadbat, A.J., Tootie, and Trixie Tang were eventually mostly phased out since.)
