She smiled down at him, and noticed him reaching for the flower pinned to his jumpsuit. He aimed it at her, and a stream of water shot out and hit her in the face. She was startled, but then began to feel very strange.
"Now you'll be like me! Adorable!" he giggled.
She swiflty shrank, her clothes drooping on her now three foot tall height. You looked at Jack in surprise, then back to her. Her head started to throb upwards, becoming egg shaped. Her hair changed too, leaving a tuft of it at the top, and two tufts at the bottom, one on either side. They stuck out and turned bright pink.
"Oooh, my head feels all silly-willy." she giggled in a higher pitched voice. She let out a fart, which now sounded like a cartoon horn. Her already large belly and butt began to grow larger and wider, giving her a smiliar, but not exact shape like the other clown. She giggled as her sandals snapped as her feet grew too large for them.
"Big feets!" she giggled wiggling her toes.
Her clothes then changed into a leotard with a pink tutu at the bottom, showing off her larger ass, and ample "front-butt"
Soon, Jen was no longer the fat slob girlfriend, but a short fat slob of a clown.
"I'm Weeble!" she said, extending a hand to Wobble. Her fingers had merged, leaving three instead of four.
He took her hand and pulled her into for a kiss, which made her giggle and fart.
"Hey, that's my girlfriend!" you said.
