Careful with the artifact you take Mr Wolf!
It might leave some side effects to your body~

Had an idea form looking at this one goofy inflation gif
I really liked the shape I thought to make an Inflated scenario using it and have our lovely Mr Wolf involved~
He tried to steal the artifact but didnt realize how it would respond next to his body!

Ofc I have my own idea with this artifact:

The Stone is a special magical artifact that can transfer water from a nearby, pool, lake or even ocean! And if a person were to hold the Artifact, they're now gonna feel their belly and inside start to stretch out and feel all of the water swelling them up, until all of the water is 100% transferred or if another person walks by and picks up the stone, making them the next victim to swell up the remaining water.

Wacky stuff haha But feel free to use think of your own ideas for this scenario~
