Keep Circulating the Tapes: Aside from the first few episodes on DVD and the Easter movie, a majority of the episodes were never released on DVD.
Role Reprisal: In the Japanese dub, unlike other dubs, some of the voice actors who normally dub the adult Looney Tunes characters also voice their baby selves here. Specifically, Kappei Yamaguchi, Satomi Koorogi and Hisako Kyoda reprise their roles as Bugs, Tweety and Granny respectively.note Albeit this isn't exactly surprising, as both Yamaguchi and Koorogi are normally typecasted with voicing kid or younger characters and Granny doesn't change too much regarding age or characterization.
In the Italian dub, that applies to Tweety and Granny. Albeit Tweety was replaced in Season 2.
In the original English version, Granny is voiced by June Foray, who has voiced Granny since 1955 and still does so to this day, even at the age of 99.
