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, but even at he best possible dps, it WILL take hours to beat. The obsidian crown will help a lot if you can get 5 octopi touching the teapot.
It drops a Giant Spoon, which is a weapon that can be enchanted to become one of the most powerful weapons of the game.
"A Teapot!"
Strategy
Black Demons from the Black magic grimoire seems to be unlikely to kill you with Enchanted Knight's Body Armor and 1000+ health.
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 Octopi touching.
