Once Sir Cole has saved the kingdom from the destructive wrath of the Underwear Dragon, he has the startling realization that the Underwear Dragon wasn't attacking because he was disobeying the signs that said not to. The Underwear Dragon just couldn't read the signs!
Once again, Sir Cole sets out on a valiant quest. This time it isn't to conquer the Underwear Dragon--it's to help him learn how to read. But it's hard to teach a fire-breathing creature to read an actual book because he sets them all on fire. And when the Underwear Dragon finally succeeds, Sir Cole presents his star pupil with the perfect gift--gigantic alphabet underwear!
