    Da alle hvalerne i havet forlader deres hjem og går i land for at bo i Jordens byer, ved menneskene ikke helt, hvad de skal synes om det. Børnene elsker det, men snart bliver byens gader fyldt med fiskeaffald. Bøndernes marker oversvømmes, da landmændene hellere vil dyrke plankton i stedet for korn. Intet korn, intet mel og dermed heller ikke brød og kager til menneskene. Folk bliver utilfredse og sure på hvalerne, indtil en lille pige spørger, hvorfor hvalerne egentligt er gået i land? En tankefuld og underholdende historie om miljø og forurening for Jordens allermindste børn.
