The Bejeweled Herring of Flatheadia, created by the powerful sage Fizzonacci, was nothing but a fish with some rubies stuck to it. Desiring to waste the time of adventurer's, he mounted this red herring on the wall of one of the runined buildings of Pheebor with a note that read:

Hahaha! Take THAT, evil villain! You've probably spent YEARS searching for this elusive fish of power, and actually all it really is just a fish with some rubies stuck to it! You spent all this time looking for a red herring, you moron! Bwahahaha! That was time you could have spent hurling fireballs at orphanages, or kicking puppies, and I've wasted it! HA! I'm so smart it's a wonder my brain just doesn't explode.

In order to lure adventurers into seeking out this so-called legendary relic, Fizzonacci wrote a paper once on his mighty herring, where he claimed that he was so proud of his creation of unimaginable powers that he immediately hid it and then pretended that he had never invented it in the first place:

Robbery, evil, phear: the upper echelons of wizardry cannot just look on as these curses take hold in our lands and our people! We must do what we can to fight off the evil in this wondrous place and help to unite all people under our banner of peace and harmony! To this end, I have created one item to rule them all! It is the Majestic Bejeweled Herring of Flatheadia, and they who own it will have power unimaginable! But they must be truly intelligent, honorable and just to control power such as this, and to this end I have hidden it, safeguarding this most precious, jewel encrusted of treasures against any but the deserving. I have hidden it somewhere which can only be reached by those with one hand, can only be seen by those with one eye, and can only be recalled by those with one single memory. Whatever else may come in your quest, all this is bathed in the rubies of my prize. May you prove worthy, or all hope is lost for our lands.

During the Great Monster Uprising, Frizzlebits and the Grand Wizard, knowing that the Bejewled Herring was a fake, found it humorous enough to send "Detective Softly" on a quest to find it (Frizzlebits had additionally planned to make him use it to cut down the mightiest tree in the forest, but the Grand Wizard decided against it). When the disgruntled adventurer returned after finding Fizzonacci's note, the Grand Wizard admitted their act of humor.
