A Sort of Magic

After a fall from a horse, Mike couldn't walk. He overheard the doctor tell his mother it was 'psycho something', so he thought that meant he was crazy. His parents were having a swimming pool installed to help him, and one of the workmen found something buried in the dirt.

What was it?

Where did the genie come from?

Why was he in Australia?

Was he going to help Mike to walk again?

Would he use a few magic words or... What?

Did Mike walk again?

Was it some sort of magic?

And what became of the genie?
