Diddo the Knave, bumbling assistant, randy adolescent and all-around lowly individual, seems to bring calamity upon the prodigious adventuring parties that employ him. A jinx, a plain fool, or perhaps both, Diddo's only solace in life is to daydream of beautiful lasses.
Returning alone after the demise of a party endeavoring to retrieve the Golden Helm of Truth for the King of Phenobia, Diddo is banned from his home city of Nyk-Nyk. Desiring to change his luckless ways, the knave sets out on his own for the Helm. Dangers lurk in the wilds of Phenobia, including flatulent whisperfowl, giant waste ticks, and tidy marsh titans, but Diddo is able to survive aided by a trio of companions: cleric's familiar, language expert and all-around fusspot Knot the Whreally Bird (a species related to the rooster with the ability to induce sleep with its call); Thin Bear, an overly emotional orphaned bear with weight issues, and Hippolyta, a pugnacious sheep replete with valor, feminine guile and the Bard's parlance.
Journeying across the land, the quartet must use their respective talents to survive such places as the Hills of Confused Livestock, the Forest of Naught and the Bridge of Conundrums, Enigmas and Other Seriously Difficult and Annoying Puzzles. Along the way there are alliesthe fearsome Misanthrope and fidgety, half-man half-rabbit Sebastian the All-Knowing Seerand enemiesthe sulla monster (an amalgamation of croc, turtle, and frog) and the two-headed tok creature.
The journey ends at the island plantation of the citrus-obsessed Marquess de Le Mon and his minions Bitchbag the Dust Witch and Vollrath the Two-Tailed Jackass. Will Diddo find the Helm, free the plantation's purple-skinned mope slaves, and avoid Worm Madness? Or is his lot in life to be nothing more than a softheaded wanker?
