Alternate Series Title: Dolphin Prince
Purported to be a series of 13 episodes. The Anime Encyclopedia reports that only three episodes of the series were ever produced, but none aired. There are conflicting sources that contend that this show, in fact, aired. Or at least the three episodes did air. If it air in April, then it would have beat Jungle Taitai to air by a full five months, making this the first color anime aired in Japan.
