Six entertaining, engaging, and educational stories – "Green-Fingers Granny"; "Am I an Octopus or an Ostrich?"; "Ultimo and His Unusual Umbrella"; "Lumba, the Lying Giant"; "Freddy and His Flip-flops"; and "Mr and Mrs Bubblepop" – aim to help children learn the third group of phonics: g, O/O, U, l, f, and b. Each story focuses on one sound and provides many words as examples for it to increase the child's vocabulary capacity for that targeted sound. The targeted sounds have been clearly highlighted using different colours to attract the child's attention. This could increase the child's later recall of that sound as well as developing the child's understanding that one letter may sound different in different words. An example for this is how the letter u in the word Umbrella sounds different from u in the word usual.
