Undercover Knight: Attack of the Underwear Dragon by Scott Rothman

Cole had always wanted to be an assistant to Sir Percival. So he wrote a letter of application.

DEAR SIR PERCIVAL, I WOULD MAKE A GREAT ASSISTANT KNIGHT BECAUSE I AM SMART, I WORK HARD AND I PROMISE TO LEARN WHATEVER I DON'T KNOW.

PLEASE GIVE ME A SHOT.

Cole's letter moves Sir Percival to tears--which was really not all that hard, since Sir Percival cried when he peeled onions, when his feelings were hurt by callous wizards, and especially when he had to fight the Underwear Dragon.

But he hires Cole, who undergoes strenuous training. He has to learn how to to ride a charger (and fall off one), how to sharpen Sir Percival's swords, spears, and pencils, and how to sooth Sir Percy when he has nightmares about facing the Underwear Dragon. He has to master knightly courage when he is knocked off a horse...,

... KNOCKED OUT BY A PRINCESS, KNOCKED DOWN BY A KNIGHT, AND KNOCKED OUT BY A CATAPULT.

At last Cole is knighted by his hero, Sir Percival, and only just in time.

The Underwear Dragon, wearing impeccable whitey tighties, appears and destroys the whole kingdom and defeats all the knights--even the (sometimes) gallant Sir Percival.

Cole is the last man standing! The Underwear Dragon is prepared to eat him up!

BUT COLE REMEMBERED EVERYTHING HE HAD LEARNED!

Cole loaded his catapult and knocked the pants off the Underwear Dragon, who became the Embarrassed Bare-Naked Dragon and flew away forever.

It's happy ever after in the court of King Arthur, in Scott Rothman's Attack of the Underwear Dragon (Random House, 2020), a new tale in the comic mode of the bungling knight and his courageous young squire, illustrated humorously by Pete Oswald, the noted illustrator of Jory Johns' humorous hits, The Good Egg, The Couch Potato, The Bad Seed, and other comic treats.
