Most people didn't actually go for that. Most people concentrated on her arms, the fact that they were abnormal, but this man had completely bypassed them and was heading toward the hollow between her arms. Considering her girth, he had quite some room to work with.
She started retracting her arms, but she'd had to start backing up, not that it helped. He was moving too fast and the uneven terrain made her footing fail. Next thing she knew his fist was connecting with her jaw and she was stumbling, falling over onto her back. Using the momentum of her gravity, she twisted her body, engorging her arm again and swinging it across to swipe him across the waist. It wasn't to grab him, but to knock him back so she was out of his reach.
