These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Word of God: Warren Robinett has said he named the dragons (Yorgle, Rhindle, and Grindle) and the Bat (Knubberrub), but only the names of the dragons made it into the manual, and Grindle got a slight name change in the process. (Or maybe not, since in other interviews he says he named the green dragon Grundle from the start)
