It was a beautiful night from outside, Gwen Tennyson was walking around, and looking around outside to make sure everything was okay at first. It looks like nothing bad happened at all from outside. Until she saw something in the distance, she saw that 3D blue sphere orb approaching her. It was called the "Blueberry Virus". She never seen this kind of 3D blue sphere orb before.

Gwen: "Wait a minute... is that the 3D blue sphere orb approaching me? I never seen this kind of strange shape energy orb before."

She kept looking at it, to see what it is going to do. After a minute, the blueberry virus charges and gets inside Gwen's body. Gwen was starting to feel weird and strange at the same time. As her stomach begin to gurgle for some reason.

Gwen: "Oh... I feel strange and weird. I didn't know that energy blue orb thingy would do this to me. Maybe I should've just stay inside the house." She then feels her skin turning blue, as she was so surprised to see that blueberry virus that is taking over her body. "Woah... what's happening to me? Why is my skin turning blue?"

Then, the transformation begins by the blueberry juice begin to fill up Gwen's entire body. Her belly and thighs begin to swell up big, so as her butt and chest that are swelling up big.

Gwen: "Oh god... this isn't good. I think I'm turning into a giant blueberry! I knew that blue orb thingy would do this to me!"

Then, her butt and thighs swelled up larger, as her cheeks begin to swell up, while the blueberry juice is filling her up. She then continues to swell up bigger and larger, then her legs got pulled, sucked, or absorbed into her huge body. Then, her body keeps swelling up larger, and larger. Then, her arms begin to swell up bigger, and it got pulled, sucked, or absorbed into her huge body. Even her hands and feet that got sucked, pulled, or absorbed into her huge body also. After the transformation, she is now a huge, massive giant spherical round blueberry. She is 16 feet tall, and she is able to move around, by being rolled, or pushed around. Since she can't walk, or run anymore, because of the loss of mobility. She could still talk with blueberry juice inside her mouth, even though, she could muffle talk while she is a giant blueberry. And the blueberry juice was leaking from Gwen's mouth, that is dripping from the corner, because she is so bloated and full. Her white shirt under a dark blue sweater that she wore, it reveals her purple belly button, and it also reveals her blue huge belly, due to her new form. But now she is rollable, if someone could roll her around, while she is a giant blueberry. But it seems that the blueberry virus is now taking care of Gwen's body. So, Gwen is going to be a massive round blueberry forever. And she could hear the gurgling, and sloshing sounds inside her huge round body, while she is a giant blueberry.

Alright, that's all! You could make your own OC if you want! Anyways, have fun!
