Those are very good
I'd only heard one of them before!
A guy gets shipwrecked.
When he wakes up, he's on a beach.
The sand is purple. He can't believe it.
The sky is purple.
He walks around a bit and sees that there is purple grass, purple birds
and purple fruit on the purple trees.
He's shocked when he finds that his skin is starting to turn purple too.
"Oh no!!" he says, "I think I've been marooned!!"
