Rocka-Bye Island

Playing with an old kayak is great fun for most of the kids, but Lee's too small to sit in it. At the cove they come across Finn Whale, who's crying because he's too big for his new tricycle. Finn and Lee soon learn that their size can come in handy.

Roisin boasts that she never brushes her teeth. Although the other children try to explain the importance of keeping your teeth clean, Roisin just doesn't get it. They hike to Whale Cove where they meet Finn, a lonely whale with a bad case of bad breath.

While tidying the school the children discover Conor has taken Ruari's plate and Brigid's favourite shell. More things start to go missing. Conor learns it's not nice to take things without asking.

Conor is unable to beat the drum in time with the rest of the band. He's got no natural rhythm. Band practice over, Mr O'Dear suggests a nature walk in the Pine Forest. There the children discover the many natural rhythms of nature.

Conor has lost his Captain Smelly doll. He soon turns up inside Conor's hood. The group head off on a hike to the Foggy Isthmus. It's so foggy the group can't even see each other properly, and Conor soon realizes he's lost Captain Smelly - again!

After hurting his leg playing football, Conor has to use a crutch and isn't able to walk very far. This gets the children thinking about how different animals get around.
