"Wellllll... it kinda happens in spurts for first timers," John said with a twitch of his rabbity nose and a shrug of his shoulders. His voice was different, odd in a way. Almost nasal. It surprised Carrie, to a certain degree, to hear her husband speak in a different voice from the one she'd come to know, but in a way, it also still sounded like him. He still had his vocal tics, he still had that slight New York accent.
"Spurts?" Carrie asked, and then, almost as if on cue, a gurgling sounded out from her belly.
With an audible "BLOOMP", her belly grew out into a round shape, and her posterior grew to match. She was now very unproportioned, with thin legs, a thin upper torso and arms, and a fat belly and backside.
"Oh, hey, what the HELL?!" Carrie shouted as she stood up with a sharp motion that caused a slight jiggle through her now-enlarged parts.
"Well, that's a surprise," John said with widened eyes as he stood up to examine his wife, walking around her. His lessened height made it much easier to see the changes up close.
"What the hell, John? You didn't tell me I'd turn fat!" Carrie moaned.
"I didn't know! Toon World makes its own decisions!" and at that, John found Carrie's hand gripping him around the skin under his neck, lifting him up to eye level as if she was grabbing him by the shirt. Thanks to toon elasticity, though, this wasn't particularly painful.
"Explain," she growled, her eyes showing the slightest hint of enhanced, brighter color.
"You don't choose your form here. Nobody does. It just happens. The theory is that Toon World... decides what is funny for each person and makes it happen. You think I wanted to be mister short stuff?"
"So you didn't make this happen?"
"No! Of course not! I love you! Just like you said before, I love you no matter what!"
"No matter what," Carrie repeated, her grip loosening.
"Of course, sweetie. You're the love of my life. I'd never willingly make you something you didn't want to be."
"Well, in that case, my little lovebunny, let's go get something to eat," she let him go, and he dropped to the ground with a "BOING", bouncing in place once. "I am friggin' STARVING, and I have such a hankering for carrots."
