Once Rachael was close enough, she lunged and tackled her clone.
"AHH!" Her clone screamed as the two Rachael's tumbled to the ground. The doppelganger dropped the box of chocolates, its contents flying all over the place. The doppelganger who was face down underneath Rachael elbowed Rachael in the face. But since Rachael didn't have a face, the elbow did not make contact. Rachael, on the other hand, used her extra arms to her advantage. Pinning her duplicate to the ground, and grabbing her flailing arms.
"I don't want to hurt you." Rachael said. "I don't care if you keep living, just give me the chocolates so I can turn back to normal."
"As if I'd believe that!" The duplicate shouted back. "After leaving you like that? If you did that to me I'd never forgive you, I'd make it my goal in life to end you."
"I don't care, just change me back and I'll let you leave, I'll even let you keep the chocolates!" As soon as those words left her mouth Rachael realized she was lying. She didn't want to part with the chocolates, she was addicted to them, she just wanted to sit in her room and transform herself all day every day for the rest of her life. But she had to lie to her clone, she needed her clone to trust her.
"I've got a better idea." The duplicate said as she pulled one of her arms free of Rachael's grasp, reached into her bra and pulled out a concealed chocolate. "I figured I might need this." The duplicated placed the chocolate in her mouth. Suddenly the duplicate's arms were doubling, no tripling in size, and not long after a second pair was ripping through her shirt, then a third pair. Just like that Rachael's doppelganger had Rachael out armed, 3 to 2, and all of the duplicate's arms looked like they could bench press a bus.
One of the new arms grabbed Rachael by what used to be her neck. Not only did this cause Rachael to lose her grip on the pinned doppelganger, but the doppelganger then effortless threw Rachael across the food court and into the wall on the far side of the mall.
Rachael pulled herself to her feet. Her doppelganger wasn't paying her any attention though. The doppelganger was busy looking through the scattered chocolate. Soon she found what she was looking for. From the distance Rachael couldn't tell what it was, but whatever it was it was dark chocolate, and the doppelganger wanted to eat it enough that she didn't even hesitate eating it off the floor.
The doppelganger began growing in size, it didn't take long for her to rip through the clothes she was wearing, but her nakedness wasn't the problem, the problem was the fact that even before the effects stopped she ate another chocolate, then another and another and another, it was impossible to keep track of how many she'd eaten. But one thing was for sure, she wasn't going to stop growing for a while. Soon she crashed through the ceiling of the mall, and just kept growing, she didn't stop until she was the size of a small skyscraper.
Rachael pushed her boobs up to look at the beast. It was as if Godzilla was attacking... well, if he was actually a giant teenage girl with six arms. And in one of those arms was the box of chocolates, and in that box was the chocolate body, Rachael's only hope of growing to the same size as Doppelzilla. Luckily the other chocolates were still scattered about the food court, unfortunately, if Rachael ate any of them they'd reappear in the box, with Doppelzilla.
"There must be some chocolates that'll help..." Rachael said, pointing her boobs toward the mess of chocolates. "Oh, but which ones?"
