Beto Tantrums Are You a Betta or a Shark?

Beto is a hysterical boy who knows no other way to communicate than shouting. He is demanding, whimsical and unfriendly. His mother has to deal with his tantrums everywhere they go. The same happens at school.
Beto would fight with everyone and because of that he is always alone.
One day, while visiting the aquarium, Beto learned a life-changing lesson, which led him to make an important decision.
