"Ok, first thing you have to do is have him show you the bitten area," the curator explained. "Then, get a sharp knife and make an incision over the bite. Then, you need to put your mouth on it - forming a tight seal - and suck all the venom out and spit it out. Make sure you don't have any cuts in your own mouth first, otherwise the venom will get into your blood and you'll die."
"Oh... and that's, um, that's the only way to save him?"
"The only way," confirmed the curator, sagely.
