Return of the Sorting Express

It's the return of the Sorting Express and the Colourblocks are on their way to Lime's In between Colour Concert. On their way, they meet Blue and Purple who have sorted all the in between colours of sunglasses for the concert, only for Lime to accidentally knock them over! Sounds like a job for the Sorting Express team, who help rearrange the sunglasses into their sections of blue, purple and in between colours. Next stop is the orange grove, where Orange is having trouble colouring flags into in between colours. It's another job for the Sorting Express team, to make and sort the flags into in between colours. At the concert, the Colourblocks forget to colour the stage. With the help of Yellow and Green, the stage is finally coloured and ready for Lime's concert. It's Lime Time!
