Juicer has no knowledge of biodrones, but I believe our rigger knows a lot about them. But ^^^ about dinos and drugs... we have no idea the amount of any toxin to use on them. We don't even know if the metabolism of any individual species is particularly resistant to certain toxins or drugs. Even with Juicer's parazoology knowledge (and parabotany... herbalism should be named parabotany for standardization), he doesn't have firsthand knowledge of dinosaurs because, well, they're extinct.
With the 3 hits he got on his parazoo roll (unless Rock wants Juicer to roll more separate p.z. rolls about individual species), he can probably tell you things similar to the theoretic behavior stuff Sam Neill's character did in J.P. 1 before they set foot on the island and everything went to hell.
Juicer's take on it IC is basically this: he's dealt with drones, no problem. He's dealt with paranormal critters, no problem. A biodrone is probably a critter that doesn't quite act the way it's supposed to, so he won't assume his behavioral knowledge is accurate. A high-powered rifle still does the same thing to them as it does to a regular critter, as far as he knows. No big deal.
