Jen held her breath, waiting to see what the transformation would bring. She looked at her naked feet with the subtly polished toenails - she was just out of bed and didn't put on socks or shoes yet - and what started as a tingle soon turned into heavy itching as rough brown hair sprouted all over them. Her feet suddenly stretched out to many times their original size, and her toes hardened into thick black claws at the ends. "Damn, how am I ever gonna get out of my pants now?", Jen thought. She didn't have to wait long for the answer: both her waist and legs began to gain mass, causing the top button of her pants to pop off and nearly ripping apart the leg seams. She now had the build of a kangaroo as well, but something was amiss...she hardly managed to stand upright on these long feet and actually had to lean against a wall to avoid falling over. However, her weight distribution finally seemed to fix itself as a huge brown tail came snaking out of her backside, growing so long that eventually half of it dragged across the floor. The growth of her tail had finally caused her pants to give way, causing them to rip apart and fall on the floor in rags. "Oh well", Jen thought, "if I'm stuck like this I'll never need pants again anyway." All the while, Diane had been looking on how her mommy suddenly grew into a kangaroo from the waist down, and experimentally let her hands slide across Jen's legs and fur to make sure it was real. Jen, meanwhile, made an even more interesting discovery as she lifted her sweater and shirt, revealing a large pouch fold on her belly. She stuck a few fingers between it and pulled it open, staring in amazement at how large this thing was. As a test of her new legs, Jen made a few very careful hops around the room and had great difficulty not knocking anything over. She then picked up Diane and said:"That's nice dear, you've turned mommy into a very nice half-kangaroo. Now, can you change mommy back as well?" Diane put a finger in her mouth and gave the Chronivac a doubtful look. "Um..."
