This is a Minecraft TNT prison and if you don't escape the box in under 5 minutes, the prison will explode and you'll be trapped at height limit with no items. The timer already started and I'm trapped in a cage. By looking around, you'll find a sponge and ice, which won't turn into water unless there's a block underneath it. There's also a barrel with seemingly nothing inside, but if you look carefully, you'll find an invisible glass pane. Now if you place it here and break the ice, it'll turn to water and you have to exit before it's absorbed by the sponge. Next, grab the sponge, barrel and mushrooms around the room, then tower up to reach the lava. The lava conceals a hidden hopper with these items and a crafting table. With the flowers and bowl, you can craft a suspicious stew with fire resistance and a bucket. Drink the stew, swim up the lava, then extinguish yourself in the powdered snow. Here, there's a candle above ice and a hidden snowball and an item frame. Then, throw the snowball through the lava to light the candle and grab the water once the ice has melted. MLG the water bucket to escape.
