This week, Geraldine and Kate's happy pants are yellow. Like the warmth of the sun, big bright smiles and really tall sunflowers swaying gently in the breeze on a warm day. And there's plenty in their pockets to make them smile, just you wait to hear all they discover. This entire episode is dedicated to smiles. How fun!

There should be plenty in this episode to makes you smile! We've got music! Fun facts! Silly jokes! And a lovely story.
