So after I got past the snake, I was in the next area and suddenly i was in the pasture. I don't know how I got there. I explored the pasture, found some bon bons, and found another yellow key. Learned how to swim, but I couldn't find where to go next, so I went back to the starting area I had been teleported to - there was a human there but I forget what they were asking for. It was a zone surrounded by green bushes for walls. I walked into the top left, and escaped.
