Rainbow Magic is the twentieth episode of the first series. It first aired on October 1, 1999.
Fizz catches sight of a rainbow when she is in the garden and thinks how magical it is. She tries to describe how colourful it was, but the others want to see one for themselves. Judy helps out by getting them to watch some on video and to take note of the many colours that are in a rainbow. They then make their own rainbow with all the colours they can remember and put it up above the window, but will they all see a real rainbow?
