A Teapot was an item announced on aniwey's Candy Box 2 Blog on September 20, 2013. Speculation led to guesses that it might be a new brewing system, like the cauldron in Candy Box or simply an item used to improve things eg. speed.
The Teapot can be found in the middle door of the Desert Fortress. It appears as an enemy with 1,000,000 (1 Million) HP and a lot of defense. It does not attack the player, however. It could take hours to beat depending on strategy.
It drops a Giant Spoon, which is a weapon that can be enchanted to become one of the most powerful weapons of the game.
Black Demons from the Black magic grimoire can be used continuously if you wear the Boots of Introspection and jump down to the second ledge. From here, you can spam Black Demons without hitting yourself since every demon in this version of the game has an empty space that aligns with where you will be (as of October 2019). This strategy goes a lot faster if you spend six pains au chocolat at The Wishing Well requesting more magic since you can cast black demons every second. If you have the lollipops for it, the Sorceress' Hat further speeds up the process although it only takes five minutes with the Octopus King's Crown with jaspers.
Alternatively you can use the Crown enchanted with obsidian, Leather Gloves enchanted to be red, Scythe, Magical red shark fin, and Xinopherydon claw, can take it down in about 5-10 minutes, if you spam with your fireball and get enough Octopodes (five is optimal) touching. On the other hand, you could use the enchanted Tribal Spear and spawn a bunch of warriors if you don't have any of that stuff although it might take longer.
