You are a woman, and you were inside Maddie Fenton's house to go check on Maddie Fenton to see what she is up to. When you entered inside the lab, you see Maddie doing her new science experiment called "Blueberry Virus" until she turns around, and she takes off her black goggles.

Maddie: "Oh, hey there! I was just testing this science experiment to see how it goes for us. You know? I wanted to try it out for the first time, since we are still friends. But anyways, let's give it a try!"

Maddie begins to pull off the tube's cap, to make the Blueberry Virus come out of the tube, until it begins to get inside your body, and Maddie's body. After that, you and Maddie were fine for a moment after the Blueberry Virus got inside your body, and Maddie's body.

Maddie: "Well, that didn't go as planned. But it did work. I told you this wasn't so bad!" She sees your skin turning blue, and her skin turning blue. "Um, that's not good. I think that science experiment made us taking side effects after that Blueberry Virus got into our bodies."

Then, the transformation begins to happen with blueberry juice begin to fill your entire body up, and Maddie's entire body also. Your belly and thighs begin to swell up, then your butt and chest swell up also.

Maddie: "Uh oh... this isn't good! I knew that darn science experiment would go wrong!"

Then, your thighs and butt swelled up larger, as your cheeks begin to swell up, with blueberry juice filling up your face. As your body continues to swell up bigger, and larger. Then, your legs got sucked, pulled, or absorbed into your huge body. As your body keeps swelling up larger, and larger. Then, your arms swelled up bigger, and got sucked, pulled, or absorbed into your huge body. Even your hands and feet got sucked, pulled, or absorbed into your huge body. After that, you finally became a huge, massive giant spherical round blueberry. You are 16 feet tall, and you will be able to move, by being rolled, or pushed around. And you could only moan, since the juice is filled inside your mouth.

Maddie: "Oh gosh! I need to fix this somehow; I don't want to end up like a giant blueberry." Then, her belly and thighs begin to swell up big, then her butt and chest swell up big. "Great.. I knew this would happen to me!" Then, her thighs and butt swell up larger. "I know this day would come. Why would I become a giant blueberry? I just wanted to be back to normal and- Mmph!" Her cheeks begin to swell up, because of the blueberry juice that is filling up her face.

Maddie's body continues to swell up bigger, and larger. As her legs begin to be sucked, pulled, or absorbed into her huge body. Then, her body keeps swelling up larger and larger. And her arms swelled up bigger, and got pulled, sucked, or absorbed into her huge body. Even her hands and feet got sucked, pulled, or absorbed into her huge body. She is now a huge, massive giant spherical round blueberry. Same thing as you. She is 16 feet tall, and she is able to move, by being rolled, or pushed around. She begins to moan, since she can't talk anymore, because of the juice that is filled inside her mouth. You and Maddie have become giant blueberries for the rest of your life for the entire time.

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