Use this seed: 3327780. You will see two big mushrooms, flowers and a lot of trees – everything you need for a Suspicious Stew. Gather two pieces of wood, make a workbench and bowls. Put two types of mushrooms, bowl, and flower into a workbench (you have to put them manually, there is no recipe in the left panel). Then just throw at another player. Done!https://minecraft.gamepedia.com/Suspicious_Stew
