Oh it's a new recipe in a server I found called dark lands survival. It's a the trampoline is actually jade to make cuz for one trampoline i have to have 7 iron ingots and I don't go mining very often cuz the mobs in the server have normal over 200 or 500 health. I'm the worst at pvp... But I normally get iron with my cacti, crops, and selling sets of armor. However that's not enough to get diamonds so instead of still mining I help some other ppl kill hydras but I just swim around them with the hydras only looking at me so they can hit it and then once it dies they give me 10 diamonds or some diamond blocks.
