A delightful story about friendship and imagination. Sam is happily eating an apple in a beautiful meadow when the apples on a tree transform into bubbles. The bubbles join together, and Billy Bubbles appears. After a game of hide and seek, Billy asks Sam if he would like to meet some of his bubble friends. But after meeting a jolly pink elephant and a cat, a nasty crocodile appears and chases after Billy. Sam soon saves the day by popping the alligator's mouth with a hedgehog's prickles, and asks Billy if he would like some lemonade at his mummy's house. But on the way home, Billy Bubbles is popped by barbed wire! Sam is sad; will he meet his new friend another day? Join Sam and Billy Bubbles, and his bubble friends, in this colourful and charming story.
