"Do I look like a troll to you?" — The Keeper of the Bridge of Comprehension in Excaliferb
The Keeper of the Bridge of Comprehension is the fantasy counterpart of Esmeralda Poofenplotz. She does not allow anyone to cross her bridge unless they answer her riddles, seemingly oblivious that the water under her bridge is shallow. She gives some complex instructions about her riddles such as categorizing them like a game show and that answers should be in the form of a haiku.
