Hey, he's offering a valuable resource! Whatever people do with it is their business, so long as none of it ends up anywhere near the people he likes. I mean, Ariados' poison is curable, of course, but in the sticks like they are? Yeah, it'd almost definitely prove to be fatal in high doses. But the shock on Taako's face is priceless, and Guzma snickers loudly as his grin only widens.

"Suit yourself, but it'd sure as heck come in handy against anything unsavory..." He shrugs, then puts his hands into his pockets, tempted to show off his Ariados, but thinks against it. With how Legolas here reacted just to the mentions of poison, who knows what he'd do to Guzma's pokemon if she suddenly appeared. Still--

"Because spiders usually come pre-installed with it, and my girl can take down a Tauros with a choice smooch, heh heh. But fine, she got more silk'n I can do with... How's 'bout that instead?"
