As soon as she woke up, Kelly knew something was wrong. Kelly was not in her room - she was in Sonia's room!
When Kelly tried to leave the room she literally HOPPED out of bed, tripping over a pair of giant feet that belonged to her, and fell flat on her face. She stood up only to find it really awkward to stand without bouncing up and down. Kelly also had some strange desire to bounce. Looking behind her, she saw a ginormous tail. Staring at in awe, Kelly let her paws (wait, paws?) fall down to her legs, trying to stabilize herself, brushing what felt like an extra layer of fur-covered skin starting from between her legs and ending at her belly. Kelly was so distracted that she fell over again!
After finding the strength, Kelly dragged herself to a full-length mirror and looked at herself with surprise, admiration, confusion, and most of all, excitement. There was fur all over her, her arms had shrunk, and a tail stretched out from behind her huge legs. The knee joints of her legs had been twisted backward, giving her a bouncy posture when she stood. Finally, Kelly looked at her belly and saw the telltale skin pouch of a kangaroo.
It suddenly made sense why she was in Sonia's room: she was in Sonia's body!
Excitement filled her and Kelly had the urge to jump up and down. But then a feeling of panic came.
"Wait a minute, if I'm Sonia, then where's Sonia?"
For the first time, Kelly let her new bouncing legs carry her over to her room where she found Sonia struggling in her human body.
