Rainbow and Posie were -not- Birds. They were cats. Cats are sleek, sweet, soft, cozy and in this very important way, they had no wings. So you can see, they were -not- birds.
So why, I ask you, was Rainbow and Posie flying through the air, with huge wings above them? How did they get there? Were they going to be okay?
Well, let's take a step back in time. Earlier that morning, Rainbow and Posie were awoken by the trill of a bird. A loud bird. Rainbow asked the bird, "Why did you wake us up? We were sleeping!"
"Oh yes, we know, we just love flying so much that we have to sing about it.", said the Blue bird, who was very blue today.
"Well, what's so great about flying?", asked Posie.
"What's so great about flying?", said the bird.
"Yes!", said Rainbow, "What's so great about flying!?"
"Well, you'll have to see for yourself.", said the bird.
"Well, I don't think that's going to happen.", said Posie, "I've have not any wings, nor does Rainbow."
"Yes, but you can get them. Call up barry in town and he can teach you how to paraglide."
"Paraglide?", said Rainbow,"What's that?"
"Well, it's a big, steerable, winged, parachute. It's so much fun, almost as fun as flying the way we do.", said the Bird, who flew away.
Rainbow and Posie winked at each other and decided to try out paragliding. So they walked to town, found Barry and got some simple safety lessons, so they wouldn't fall.
So, the next day. Rainbow and Posie were with a fellow, attached each to one paraglider person and in the air before they knew it. It was, indeed, something to sing about.
