Herda, malenʹke kytenyaty. U nʹoho shchaslyve dytynstvo. Ale stayetʹsya shchosʹ nespodivane i Herda zalyshayetʹsya odna bez sim'yi. Pochuvayuchysʹ sumnoyu ta samotnʹoyu, vona podorozhuye okeanamy ta zustrichaye novykh druziv: kosatok, pinhviniv, chayok i navitʹ vosʹmynoha! Kozhen iz novykh druziv navchytʹ yiyi chomusʹ tsikavomu. Herda ne tilʹky diznayetʹsya, yak zhyvutʹ inshi meshkantsi moriv i okeaniv, ale y vidkryvaye dlya sebe zakhoplyuyuchyy svit mistsʹ, de vona plavaye. Ta chy znayde malenʹka Herda te, shcho shukaye?
