Flo and Mum are busy and Bird is talking to the ducks, which means Ebb is left on her own. So she sets off to find someone to play with. Suddenly, there's a little cry 'Wah! Wah!', it's a baby seal. At last! A friend for Ebb! But the baby seal is a long way from home. It's up to Ebb and the family to find the baby seal's mother.

Mae Flo a Mam yn brysur ac mae Bird yn siarad gyda'r hwyaid, sy'n gadael Ebb ar ei phen ei hun. Wrth grwydro i chwilio am rywun i chwarae gyda hi, mae Ebb yn clywed cri morlo bach sydd ymhell o'i gartref, a rhaid iddi hi a'i theulu ei helpu i ddarganfod ei fam.
