He's glad that Guppy's able to stun the monster's fingers, but Duster's worried about what those snake fingers can do if they start working again.

He circles around the monster and reaches into his pouch, pulling out what seem to be two oversized staples. Once it's looking at Guppy's direction, Duster leaps and attempts to pins its arms onto a nearby tree and hopefully do the same for its legs.

Unfortunately, trees are not ideal surfaces for Wall Staples, and the monster easily breaks the one arm poorly pinned down, now hissing at Duster. It bites at him, and while Duster dodges the worst of it, his arm now has a noticeable cut.
