Fast!

It's a race to the treehouse, but Nick and Sally wish they could go as fast as an airplane. "How about a peregrine falcon?" asks The Cat. His friend Perry the peregrine falcon, the fastest creature in the world, will show them how fast he can be. Off to Steep-and-Deep Cliffs to meet him. Using Cat's special backpacks, the kids have wings like Perry's so they can fly through the air too. Perry shows them how he dives straight down to catch his food. Who wants to be as fast as an airplane, when you can be a peregrine falcon.
