Nobody talks about this one. Josephina is a whale who remembers being human, and the show treats that impossible thing as quietly true instead of magical. You watch her move through a world that has no use for what she knows, no frame for what she's become, just the daily weight of being alive in a body that doesn't match the person inside it. The 1979 animation doesn't fight for your attention. It just holds the space where grief and acceptance meet, and asks you to sit there with her. Most fantasy wants to dazzle you. This one wants you to understand what it costs to survive transformation.
Santi is a shy Spanish boy with an unusual secret: he keeps a tiny whale named Josephina in a bowl, and no one but him can see her. Josephina can change her size and take to the air, and she carries Santi off on a series of dreamlike adventures while helping him face the difficulties of growing up. Things begin to shift as Santi grows curious about the outside world and comes to know his distant father. The 1979 fantasy TV series is an adaptation of Adios, Josefina by Jose Maria Sanchez-Silva.
