Where is Micca????? Well, I just looked it up, and here is the answer...

Micca is on page 630 between "Micah" and "mice".

It says:

Micca - Dwarf-like inhabitant of Middle-Earth in the Tolkien mythos, possessed of a stocky, powerful body, quite hairy, with extremely bushy black eyebrows. Miccas startle their foes on the field of battle by suddenly raising their bushy eyebrows, grimacing, and uttering a hideous ululating warcry. They eat watercress and haggis. They are unpredictable in the extreme.
