About the hippopotamus who was afraid of inoculations (1966)

Fabulous animals bathed, rested and had fun on the summer beach of the southern town. Suddenly, the rest was interrupted by an urgent message on a hanging poster: "Everyone needs to vaccinate vaccinations from elephant to fly!". However, all the animals, having read the message, as if nothing had happened, began to rest, dance and sunbathe again. And only Behemoth, worried, began to ask everyone how scary and painful it was to vaccinate.
