Usopp himself only found it slightly amusing; the more important thing was that it would work, and he puffed up at bit at Sai's compliment. "Thanks, it took me a little while to think of it." In a way, he was grateful for Sai's stopping his attack so handily last night. It would have been a waste considering how little good it would have done, and now he still had some ammunition, even if it wasn't very powerful.

"We can try to find some more things for you, too, although you're really handy with those trowels." Usopp hadn't yet forgotten the first night he'd met Sai, armed with garden tools to face down the horrors of death slugs. "We'll probably be okay at least for the start of the night. And we can always run if anything seems too tough."
