The chest isn't a boss in the chest. You chose to include bosses from the cellar, but no other floors from WotL (catacombs, necropolis, utero) Except for cathedral and the chest. You forgot some alternate bosses, such as Conquest and the Headless Horseman, as well as Tri-achnid. This seems like a lot, but it's not in comparison to what you DID remember. Well played.
He forgot Conquest, Headless Horseman, SATAN, The Fallen, Lokii (aka Loki 2), Daddy Long Legs, Triachnid, Carrion Queen, The Hollow, and The Husk. Also, to get The Duke of Flies and The Bloat, you *have* to type 'the', which shouldnt be necessary. The Chest is not a boss, he misspelled basement once, he left in a blank column in the middle, and ??? seems to be an answer to any 3-letter entry so anyone can get it right away. It SHOULD only accept "Blue Baby" or "Unknown".
