Aqua's Hippo Heaviness

Aqua's journey to find Ven and Terra was tough, even though she was a new Keyblade Master and knowledgeable on keeping the darkness at bay. Despite knowing paths of flight, however, at a point she became lost between worlds, unaware of where she had landed, however the world was filled with many fauna and animals.

As the blue haired woman landed, she looked around, noticing many animals in the distance, particularly two lion cubs and a blue bird following behind them.

"This world is full of life," Aqua observed with a grin on her face.
However, she noticed the armor on her shoulder glowed, the magic within changing her to make her match her surroundings and blend in.

Aqua waited, wondering what would happen before she noticed her nails blacken, turning a darker color as she stood there, though she noticed her shoes felt  bit tight as well.

Curiously, she waited and watched, but she suddenly felt her shoes and accessories burst, her legs turning thick and wide, while her foot looked stumpier. "What's going on?"

With confusion, she looked at her hands, seeing her fingers shrink as her hands followed suit, becoming exactly like her legs. Aqua was still reeling from the change, when she noticed her belly poking outward, growing heavier and bigger. Soon, it was jutting out, a pale, tan color as Aqua's body continued to fatten.

She tried to touch her face, losing balance and falling on her rump with a loud thud. Aqua felt the poking of her new tail beneath her ripped clothes.
As shreds of her black and blue clothing began to litter the ground, Aqua felt her face, eeling her jaw and nose shift as her mouth grew bigger, while jowls and wrnkles of extra chins appeared beneath her mouth. The cyan eyed keyblade wielder felt concern as her ears changed next, slowly realizing she had become a hippo.

She sat there as the changes finished, feeling dismayed as her titanic tummy's bottom began to brush against the grass beneath her body, wedged between her jiggly legs.

"Well, this wasn't what I was expecting," Aqua sighed to herself. With a few scraps of clothes still clinging to her blubbery body, Aqua snorted before getting on all fours, her belly hanging low as she tried walking on all fours, trundling towards a nearby river.
Looking into the water, she took stock of her fattened and transformed body, displeased with it. "How do I even use a keyblade like this?"

Before she could ponder it too much, she waded into the water, a small smile of relief on her face as she felt more comfortable before hearing... "Singing?"

Looking over, she saw the lion cubs and bird from before singing, the male cub talking about being king. Aqua wasn't fully sure what was going on, but felt an urge to sing along. As she swam nearer to the commotion, she began to wonder if she could get used to her heavy, hippo form.
