You feel it first, then see it, the cat-girl you're on, still not awake, now getting bigger under your feet. You try to slide off at first, but the growing happens too quick and the you find yourself getting tangled in her strands of hair. Her quiet sleepy grumbling becoming louder, and the subtle sounds of her swishing tail increases as it now is sending out shots of wind each time it flicks left and right. The couple runs as those feet approach them quickly, becoming bigger as they grow their way. As well the mermaids panic to swim away, putting up with the shark when they see a huge cat-eared happily snoozing face growing and making its way over to them. It isn't until she's grown big enough for her chin to touch the edge of the water for both the growth to stop, and for her to wake up.
Feeling the water on her chin, interrupting her nap, the cat-girl swipes her face to wipe it all off. She sits herself up and stretches out, eyes closed the whole way. Shockingly her yawn came with an echo. She pops open her eyes, and her ears twitch as she looks around, no longer seeing the beach, until she looked down. The distance of sand that was between the fields leading to the forest, all the way to the sea, was now taken up just from her ankles to her knees. "I'm huge? How did that happen?" she keeps moving her head around looking at the ground, admiring the surprise.
You in the meantime, where between her strands of hair like a flea, but somehow even smaller. You're launched and repeatedly swatter by her strands of hairs. You can't escape the jungle until you see the hair trees collapse before you, finger tips broke through the structures, her nicely done nails, nearly claws, scratch her head and almost swipe you in the process. When the hand leaves you see a good hole left open as those strands try to rise to their original spot. You charge out to that opening, only making half the distance before the floor, her scalp launches up and takes you high. The force of her rise feels like you're being pushed down from above.
"This is AWESOME!" she says as she tries jumping to her feet. Not taking into account her size and the works of gravity as her leap up sends a large cloud of sand up and out in a shockwave around her as she leaps to her feet. She walks around looking for the people that were here, ready to explore at her size, the dancer cat swivels her body as she spins in place, smiling down at everything around her, now so easy to get to. Her tail wildly excitingly shaking. What should she do she wonders.
You again are stuck in strands, except not on the scalp this time, but up high in her hair tips, one easy scratch away or quick flick of her head to launch you out like a catapulted projectile. You hope whatever she's doing either frees you, or isn't so full of thrust motions
