At the school, the group are getting ready to go to Otter Creek for a picnic. While Ruari gets their lunches ready, Lee and Conor argue over who is getting more bananas and who’s getting less. Later at their picnic spot they come across Orin the Otter, who happens to be getting ready for his own picnic with Clodagh the Kingfisher. He’s having trouble figuring out how many fish he’s got in his two piles. With the help of a song from Glammie Guppie the rock star, Orin and the children learn how to tell which pile has more and which has less.
