Hatty Hattington is the antagonist from the Behemoth game BattleBlock Theater, and is the only character in Castle Crashers to have a square head.

DLC Contents

• Hatty Hattington
• Golden Whale
• Emerald Sword

The Golden Whale is the new animal orb which ocassionally defecates a cube of gold worth one gold coin. 

The only weapon that comes with this DLC is the Emerald Sword, which is the green sword on the far right in the picture below. There appears to be a glitch where if you unequip the sword even once, it disappears from the weapons frog. Resetting Hatty seems to solve this problem.
