Of course if you haven't made a cobblestone generator yet, make one. Here is my full list of ideas: XP Farm (Tutorial) Iron Farm (Tutorial) Wheat/Melon/Pumpkin/Carrot/Potato Farm (Automated Melon Farm Tutorial) (Resource Friendly) Animal Farm Shop Make a house Expand your island If you would like any more suggestions, please contact me by leaving a comment on my profile.
(I removed my shop because it was using a lot of time for me, I earned a lot from it but it's annoying to restock every day.) You know what I did when I was out of ideas? I made a giant 'biome' and, I made a giant 'plot'world with 4 plots. The giant biome became a hide and seek, and the plot world became the islands chest room and my main island. I made another layer under my 'farm' island, and that layer is going to be full with heads. (I take it from the people that are online.) In my 'farm'island I made a lot of recourse farms. (Mob trap with 8 spawners in it.) (I replaced that mob trap with a different design, also 8 spawners.) (A goldfarm with 8 spawners set on Zombie Pigmen.) If I could go online I would continue making more farms, and making more pixelart above my hide and seek. I don't know if you have beacons but you can also try that.
