Well, as risky as it was, the only option that really helped Blake's goal of getting back to New Opal was to get help, and to get help, he had to first get the princess's attention.
"Hey! Down here! Miss!" Blake thought about calling up to Camilla using her name or title, but decided that it would be better to act like he had no idea who she was. After all, if he, someone she'd never seen in her life before, addressed her as Camilla or Princess Camilla... well, that might look a little suspicious, and now that he thought about it, Camilla wasn't known for being merciful to people she viewed as an enemy.

"Mmm... let me thing about it..." The huge princess hummed thoughtfully, dangling Blake in her fingers over the enormous shelf of soft, plump flesh waiting below him. A-at least if she dropped him he'd have a soft landing...
