The Fairly OddParents! has crossed over with and/or appeared on several fellow Nickelodeon series over its 16 year run. During Season 4 and Season 5, three hour-long episodes were broadcast in which The Fairly OddParents characters met characters from The Adventures of Jimmy Neutron: Boy Genius. The third of these special episodes was intended to be the series finale for both, until FOP was eventually uncancelled and renewed for a sixth season. In 2017, several Fairly OddParents characters appeared in fellow Butch Hartman show Bunsen is a Beast, in an episode titled Beast of Friends.
