Blacksmith

Blacksmith
The Blacksmiths is a previously unlocked place in Castle Crashers. It can be visited any time wanted, But you may not go in the dark tent seen behind The Blacksmith himself.

It also holds a Golden Clock, which you can pick up and is needed for setting sail at The Docks.

Wepfrog
The Weapons are stored inside of The Giant Frog, who is also known as The Wepfrog. He looks small, but when inside  him he is very large and long, with a rope tied to one side of him holding your weapons, displaying the stats for them if you walk past. New weapons will automatically be stored there, excluding the bow, when you collect them in battle.

The music playing outside of The Wepfrog and in The Ark will stop, and will change to dripping and silent roars.

There is no story behind The Wepfrig or how he was defeated and tied up there, but The Blacksmith probably killed him when he was tresspassing onto his land.

Animal Ark
The Animal Ark is where collected Animals that were found in battle or bought at a shop are stored. Up to four animals  can be stored in on habitat, and each animal has a diferent habitat, if not the same as another. When an animal is following you, if walking over the the chalkboard next to the nurse some infomation will appear on it about that animal's abilities.

There is also a bin, for discarding animals. It does not rid them from the game forever, just sends them to relax in their habitat. To get a animal from their habitat, simply walk over to them and they will come out and follow your knight. Only one animal may follow at a time.

Blacksmith (character)
The Blacksmith himself is said to be The Purple Knight, as he wears a chestplate with a coloured add sign on like a playable knight. Obviously, it is Purple as he is said to be The Purple Knight.

The Purple Knight is also unlockable, and is The Pink Knights boyfriend, who is said to be the nurse. But, there is no solid evidence marking these to as married. However, there is alot of fanfiction and fanart about this.

His magic attacks are, as said by Castlepedia, are preformed by:

Splash Attack: Antlered Frog Tongue-Shot(+) As a playable character/unlocked character, he appears with a Purple Helmet with Purple Antlers on it. As an NPC, he holds a hammer and forges swords without his helmet, weapon or sheild at the Blacksmith. The arrows he fires are silver, and is avalible on the Xbox 360 Live Market. However, some Asian and North American players had to download the DLC character pack to get him, but only a week passed before he was released on the Market in them places.
