Kujira no Josephina

Santi is a shy Spanish boy who keeps a tiny whale in a bowl, invisible to everyone but him. The whale, named Josephina, is able to alter her size and fly; she takes Santi on many dreamlike adventures and helps him confront the challenges during his childhood. However, things change as Santi starts taking interest in the outside world and gets to know his distant father. — written by Singan Note: Episodes 23 and 24 (a two-parter named "Sayonara Josephina") were not initially broadcast. Only during a re-run in January 1980 were those episodes finally shown. * Based on Adios, Josefina (Goodbye, Josephine) by Jose Maria Sanchez-Silva.
