Ep 15. 'O' and 'Z'

Everybody is playing outside and having fun - all the letters are using their powers and have transformed. 'z' is sad that he cannot play along. 'z' is the only letter who hasn't learnt his sound and shape. He is wondering why he is always last. Luckily, friendly 'o' helps him realize how to turn into things beginning with his sound so that he can play along too.
