🔒Locked chests were added to Minecraft as an April Fool's joke in Beta 1.4 on April 1st, 2011.
💣Locked chests were indestructible, except for explosions.
🧩Players could combine locked chests to create double locked chests.
💡Right-clicking a locked chest triggered a popup with a message about a fake Minecraft store.
🛒The fake Minecraft store allowed players to buy crate keys and other items as part of the April Fool's joke.
