The anime is about hula hula dancing...Not babies in the sky
The official website for the anime of Flying Babies will premiere in January and revealed a visual which you can see above.
Anime News Network describes the story as follows:
“The anime will center on a group of young girls and their struggle as they aim to become Hula Girls. In Japanese, the characters for “hula” in the phonetic katakana alphabet and the first two katakana characters used in the word “flying” are the same.”
