I Am Error
A semi-popular phrase from the second Zelda game - Zelda II: The Adventure of Link. Typically useless, but has one small line besides his trademark that is actually a hint.
Was named as a joke, as there is another NPC in the game named Bagu that looks the same. Bagu was supposed to be "Bug."
I talked to the purple guy, but all he said was "I AM ERROR."
