De sultan van Zanzibar heeft een probleem, want zijn haven wordt geterroriseerd door haaien. De sultan laat daarom 12 nijlpaarden in de haven los om de haaien te verjagen, en het probleem is warempel opgelost. Nu de nijlpaarden niet meer nodig zijn, laat de sultan ze afmaken, allemaal op één na: een klein nijlpaardje genaamd Hugo.
Nee, helaas is Hugó, a víziló nog niet beschikbaar op Netflix in Nederland.
