I've killed three Bigfoots so far and every time each of them dropped a Pig Head, Tree Branch, Leather, 100 NX and some mesos. I believe it's also the same for Headless Horseman having a static drop with no chance of Jack o' Lantern, but I haven't killed too many of them.
I think the toe rate is far lower than 33%. In my experience a toe drops every 5-8ish BF's. I think if you go over 15-20 without seeing a toe then it would be a serious issue but BF toes are usually pretty rare. The same applies for HH. Disclaimer: This is all from personal experience so the numbers may be off
Figured it out. Just seemed a bit weird at first seeing as it was one of the first times I fought Bigfoot.
I've hunted like 10 bigfoots and still no sight of toe. Is it only me? EDIT: nvm, just found 1 today. We're good
