Hips
Hips. They were like creations created by some amazing artist. The way they rocked when one walked, and how they would sway to the music. They were such beautiful things.
That's why Tigger loved Rabbit's so much.
He loved to tickle the hare there. The orange creature adored giving hugs there. And of course when he gave his special bounce, Rabbit's hips were the place to aim. And when the yellow critter wore his apron, of course his grin was from how it hugged the bunny's waist.
It's funny how Tigger was the only one in the 100 Acre Woods to understand that it truly was "all in the hips".
