The locket

Emily and Ruby were having their usual morning walk when they found something

shining brightly on the floor. The light was SO bright that it almost blinded them!

Very confused, finally they picked it up. It was a locket of a peacock's

feather. It had a key to go with it but fixed on a bracelet. Oh, what was it?

As quick as a flash they were whisked away to the wonderful world of :

COLOURS. There was vibrant colours everywhere. Where were they? What was it?

What had this got to do with them? How would they ever get out?
