Psychedelic, Jumpy

Set against a rainbow sky,
Splashed red and black, green and blue; yellow, violet, orange too!
Beautiful shades; in the foreground, a man.
He looked up at the sun, not that it could be seen
Praising his stars for what had just happened,
Followed by a cry of joy, spread across the sky,
A jump so high, happiness abound!
It lightened the mood of those around.

What happened then, nobody seems to know,
Well what made him happy? Find out, do try
And try it out yourself; trust me, it's nice!
