In the box of vials was a large section dedicated to different species of plant, and they were all neatly contained in a plastic grid. Mary (as carefully as she could in her final moments of awareness) grabbed the plastic organizer between 2 giant fingers, held it upside down over her mouth, and watched as the contents from each vial splashed into her giant mouth.
Mary sprung upright and awake with a movement that slightly shook the planet. She instinctively tried to pound SNOOZE on the alarm clock at the left side of her bed, but instead accidentally used 4 arms to flatten the ruins of 4 houses on the left side of her street. Mary's hunger pains had subsided from cosmic levels to regular starving-human levels, which was good enough for now. Judging by the sunrise, Mary had been asleep for at least a day, but her gut told her it had probably been longer.
Something felt different about Mary's body, so she stood up to investigate herself. The giantess's skin had a rougher texture and shifted slightly towards a green hue, but her nipples, lips, fingernails, and pussy had completely turned a deep green. Exotic flowers bloomed from each of her earlobes, resembling earrings. Mary's canine teeth had turned quite a lot sharper (she didn't know what plant could've caused this, but it looked cool so she went with it). Arrays of thorns circled the wrists of Mary's topmost 2 arms. Her tongue had become long, narrow, and vine-like, and it was now totally prehensile.
As Mary stood up and exposed more skin to the air, she felt a pleasurable tingle as more skin began converting CO2 and air moisture into energy. Every cell of her body that was lit by the rising sun felt an even stronger tingle! Across the giant body, splotches of short, soft, *sensitive* grass grew. Proudly, Mary faced the sun and split her 8 arms between caressing herself and absorbing the sun's sensual rays. Everything felt godly! Golden sap dripped from the photosynthesizing giantess's nipples and pussy, and where it landed small grass and flowers suddenly flourished despite the barren state of the suburb-turned-wasteland. Mary's hunger wasn't fading fast enough, however. No matter how hard she tried, the hunger was too distracting and always left the green-tinted giantess just short of finishing. Mary even tried drinking several more Height+ Vials to increase her surface area, but it was futile and only made her more hungry. After 5 vials and reaching a staggering 266' 5", she was only starting to feel woozy instead of sexy.
Mary drooled with hunger and angrily wiped the fluid off her face. But rather than human saliva, Mary found a mysterious boiling liquid that tickled her invincible hand. Acid like a Venus flytrap! This gave the plant giantess an idea as she walked towards a nearby overturned car. Mary effortlessly picked up the car by its hood with her index finger and thumb, and brought it to her mouth. It was like playing with a little die-cast toy! Suddenly the back half of the car snapped off under its own weight and careened 266 ft to the ground. What once would've been an impressively deep crater left by the car-half was now barely noteworthy in comparison to the powerful giantess's casual footprints. Annoyed, Mary let the front half drop too, then used her lower arms to scoop up the car and its surrounding road. She effortlessly rolled the asphalt and car into a ball with her palms like it was dough, passed the ball between her sets of arms, tossed it in the air, and caught it in her mouth. Mary moaned in pleasure as she rolled the 2-ton ball with her vine-tongue and felt her acid get to work. The ball melted in Mary's mouth as fast as an ice cube in a human's mouth. It was the most delicious thing she had ever tasted, but she felt it could be even better without the asphalt. Mary did appreciate the spicy kick when her acid mixed with the car's gasoline and caused a huge fireball inside her indestructible mouth.
Mary continued her delectable car-eating rampage, now remembering to crush the cars into cubes before lifting them. The fuel in the cars was a great source of energy for the ultimate (yet still improving) life form. What would she do next?
