Hatty Hattington is the co-main character of Battleblock Theater with the objective being to save him. He is a DLC/Character in Castle Crashers, unlocked by purchasing the Can't Stop Crying Pack or Insane Store on Xbox One. His magic is non-elemental and based around Money and items as well as references to Battleblock Theater.
Cubes of gold rain down from the sky to in front of the character in sets of four. Each set of four cubes is accompanied by a fly by of an oversized Golden Whale that swoops in from the top. Knocks enemies over and damages them (and can only hit an enemy that is knocked over once, no matter how many gold blocks or whales there are (bosses are an exception, seeing as they cannot be knocked over (exceptions for enemy minibosses e.g Conehead Groom))).
There are no bonuses to this spell, but there are a few definite drawbacks. When casted, there's a 2-3 second delay before enemies are hit. Any magic splash that falls from the sky is nerfed by speed anyway, but this is the most nerfed attack of them all. It's not rapidly damaging either.
Hatty Hattington, as well as Bear and Saracen, have a unique RT+A+Y/A+RT+Y move that is different to the rest of their moveset. After pressing the buttons Hatty will throw a giant green gem to the ground, doing normal projectile damage. This attack is similar to Pink Knight's Stuffed Animals, but Hatty's gems don't critical hit enemies like the stuffed animals do.
Hatty's beefy form makes it appear as if he had folds of belly fat. It is, in fact, just the shirt he wears under his coat.
Hatty has the longest splash attack delay of any character in the game.
Hatty is one of the only characters with a dynamic magic projectile. (The others being Bear and Saracen)
Hatty is the only character that can DIE before his splash hits enemies.
Hatty's Magic attacks are references to his game of origin: BattleBlock Theater. The golden whale can be seen in the opening cutscene and a special arena mode called "Gold Grab", gems are collected to complete levels, and you can pick up wings as a power up that temporarily grants you the ability to fly. As for the tears, Hatty started crying when the hat was first put on his head.
Hatty is an E Rank character (E-).
The green laser at the end of Battleblock Theater might have been his entrance to the game. This is disproven by Pit People's ending.
