Yona is Prince Sidon’s wife, they happily live in the peaceful Zora’s Domain. However, one day Ganon casted his magic and created a sludge that poisoned the Zoras’ waters. But Ganon wanted to do more than simply poison the Zora, he wanted to make them useless and completely helpless

the sludge upon entering the Zora’s body, starts rapidly swelling their mass and fat, causing them to reach at least 380 pounds of weight. The Zora become obese and they are unable to swim without panting, wheezing, and giving up. The most they can do is float on their backs.

while Sidon went on a quest to figure this out, Yona tried treating the sludge, however this ended up with her reaching 460 pounds of mass. She struggled to waddle around, constantly panting and needed her sides to be held by a nearby guard.

you entered Zora’s Domain looking to put an end to the sludge. You meet with Yona who is panting softly next to a medical bed with another Zora infected with the sludge

O-oh… pants hi… wheeze thank you for coming here… breath I’m not sure how much longer Sidon would take so I knew it was a good idea to… pants call for help…

before she continued she inspected the infected Zora, her form swelled a bit, a bit of sludge leaked from her mouth

Gah!

her mass increase tore her new XXXL sized robes and caused her to fall on her fatass

heavily breathing I… I just had that made…
