Once I found a giga with my tribemate in the highlands. We were planning to grapple onto its back and shoot it, so we gathered the supplies. We then flew over the giga, and I dropped myself with a parachute to grapple onto the giga and knock it out. Sadly, I missed the shot, and got eaten. I then tried to get my stuff back by taking my items and running into a nearby cave. What we did not realize yet was that the cave was big enough for the giga to go through, and I lost my life. Lesson: don't try and repeat stuff from reddit
