I was fooling around with hopper minecarts, and I came up with this for the Hermit Holes golf course/experience. If you have no idea what I'm talking about, go watch this video. Also, if you are a hermit, then I'm honored that you are on this page, and, of you choose to use this idea in Hermit Holes, feel free to change it in any way, shape, or form since it's just an idea.
Note: This is the first page I've ever made, so if it sucks, constructive criticism is appreciated, but if you don't like it, please say why and not just "IT SUCKS". Btw, drink a night vision potion (if it's not in your hotbar already) and look to the left to see the Ocean Monument. Feel free to edit this in any way shape or form, but if it bears resemblance to the original, please give a bit of credit (i.e. if you just get it for the seed or for personal use don't worry but if you use it to make a public build based on or around the stuff I've built, link this page or something.) Also, the screenshot wouldn't process so I just used a blank white square.
