We just need to invest in some thick gloves, preferably ballroom length, and cover up our legs and feet as well. I love the idea for using them on Kangaskhan, although before all this we should probably go shoot that Nidoran female beforehand to get the poison. Could probably capture Silver's Nidoran on the way, and maybe a female one for us as well if we decide to go for that over oddish. What with the fatal poison, ability to dig - we have a pit fall trap maker on hand-, sensitive hearing and senses -could train it to notify us of things like people approaching us-, it can learn Toxic Spikes so we could just keep a bag full of pre-toxified spikes around or have her make them on location, we could get great type coverage by teaching it thunderbolt and icebeam, it can learn a large amount and variety of TMS, it has only two weaknesses and FIVE resistances, and it doesn't have the stink problem of oddish -> Gloom, and we don't need to bank on the oddish and us lasting long enough to get to Gloom to use that strategy/worry about that, since Nidoran are useful immediately since we can harvest poison off her. Also we can breed her with Silver's if he gets a male. So that's a bonus.
Also with the new information on time in mind, since the Kangaskhan research isn't as pressing as we thought, I propose we research Nidoran, specifically the female ones if it must be specified. Even if in the end we don't decide to capture one, knowledge of it's poison will prove useful in the Safari Zone if we can shoot one, as even if it would be risky to use on the Kangaskhan, we could still just pump it's corpse full of it. That, or leave a nasty suprise for any pokemon who try to eat the corpse by stuffing poisoned caltrops into it's body if we can't just poison the corpse.
Still, researching Nidoran poison is also good in case someone like Silver gets poisoned in the process of capturing his Nidoran, so we can make sure we know to have or make an antidote.
