Adventures on Rainbow Pond (partially found Harmony Gold English dub of "Demetan the Frog" anime series; mid-late 1980s)
Adventures on Rainbow Pond (also known as The Brave Frog and Demetan Croaker) is an English adaptation of the TV anime Demetan The Frog (けろっこデメタン Kerokko Demetan), produced by Harmony Gold at some point in the mid-to-late '80s (exact year unknown). It covered approximately 26 episodes of the original 39-episode series
Harmony Gold had also released the Demetan anime as two compilation films titled "The Brave Frog" (in 1988) and "The Brave Frog's Greatest Adventure" (in 1989).
While the two compilation film dubs have circulated around and have been widely seen, nothing has surfaced of the Rainbow Pond English incarnation. However, this version was used as the basis for a few international dubs, such as ones aired in Germany, Portugal, and Saudi Arabia.
It has been alleged that there were a few localization differences between this version and the compilation films, with the love interest character (Ranatan) being named "Pookie" in the two films but "Hilary" in the series. The German dub did localize the same character's name to "Hildegard" in their version of the TV series that was based on Harmony Gold's version.
A copyright catalogue of Harmony Gold's titles suggests that the rights to this version were held until at least 1996, along with The Magical World of Gigi and a dub of Temple the Balloonist that was retitled "Sabrina's Journey".
On September 14th, 2014, the full English version of "The Brave Frog" was found and uploaded to YouTube by user Григорий Нестеров.
