“Wow! I’m roly-poly,” Numbuh 3 said as her hands roamed over her body. She felt her massive gut, weighing it in both hands and pulling at the folds of fat on her sides. She wordlessly groped, rubbed, pressed and pinched all over her bulging body before a wide grin split her face and she giggled. “Cool.”

“This is most…. odd,” Numbuh 1 stammered as he stared at his plus 5 teammate.

“Understatement of the year,” Numbuh 5 snorted. Kuki had become the biggest Kids Next Door operative ever. She weighed more now then two teens. Everyone was very apprehensive of getting closer or even looking at the enlarged oriental girl. Especially Numbuh 4 who seemed to be struggling with revulsion, awe, worry and some other emotion that was making his crotch feel funny. He decided to just stare with his mouth open and not say anything stupid.

“I’m big,” Kuki giggled and dropped back onto the floor. Landing with a thud, she wiggled her sausage like hands in front of her eyes and kicked her pudgy legs in the air. Everyone’s eyes shot open and their mouths dropped. Numbuh 3’s shorts had ripped when her ass grew ten sizes and from her position on her back with her legs in the air, they got to see a lot more of her large caboose.

“Igottogetoutofhere!” Numbuh 4 rushed out of the room as fast as he could to the nearest bathroom. He had no idea why he had this sudden urge to be locked in a bathroom after seeing Kuki’s ass partially, but his instincts screamed for him to go. Everyone else who didn’t take any of the serum just covered their eyes.

“Numbuh 5, do something!” Numbuh 1 commanded.

“Me, why me?”

“Because you’re a girl! Its okay if you look at…at…that!” Numbuh 1 rationalized and Numbuh 2 backed him up, neither boy wanted to get within ten feet of their fat friend in the ripped pants. Numbuh 5 looked at the boys angrily, cursing softly at them before walking slowly towards a still horizontal Numbuh 3, who had lifted up her long green sweater and was poking at her pudgy pale gut. Her finger pushed into the soft bulge, sinking several inches down right to her knuckle. Kuki giggled, loving her new softness. She was like a rainbow Monkey now, soft and huggable. Strangely though, the one person she wanted to hug more then anyone was Numbuh 4. Wrapping her arms around him and crushing him into her new softness sounded very nice.

“Numbuh 3! cut it out!” numbuh 5 hissed as she stood over her friend. On her back, Kuki’s belly nearly reached Numbuh 5’s chest, making the girl feel even smaller before the tubby preteen. Kuki stopped playing around and stared up at her long time friend with a happy smile.

“Hiya Numbuh 5! Isn’t my new body really cool! I’m all round and soft, like a big furless Rainbow Monkey. Would you like a hug?” Numbuh 5 flinched as Kuki reached her thick, blubbery arms out to her friend for a big, full body hug. Getting those meaty arms wrapped around her was something Numbuh 5 didn't want one bit. Backing away from the overly energetic girl, Numbuh 5 tried to calm her down.

“I’m no hugger Numbuh 3, try hugging someone else. I hear Numbuh 4 loves a nice, big hug,” Numbuh 5 said with an evil smirk. That would punish that Aussie jerk for running off on them, let him deal with Hugzilla. “Now, you were such a good sport for taking the serum, how about some candy.”

“Candy!” Kuki screamed, suddenly realizing how hungry she was for something sweet. Jumping to her feet, she nearly pushed Numbuh 5 over as she rushed to get some candy. The three remaining KND members watched her rush away, her jiggly butt swaying as she ran. A silence fell over the operatives, all of them thinking about the repercussions of what had happened.

“I’ll have to report this in. It seems that the H.A.T.E. serum is a failure, but at least we didn’t lose anything important because of it,” Numbuh 1 commented, seeing Kuki’s transformation as not that bad of a thing. So she was bigger and needed more approperate clothes, she was still a member of the Kids Next Door.

“But we did lose something important!” Numbuh 2 screamed, grabbing Numbuh 1 and shaking him. “Numbuh 3’s going to eat all our candy now. We’re doomed!”

“Idiots,” Numbuh 5 groaned and walked off, leaving the boys to mourn their candy.
