A lapinemoth is a 9-foot-tall, talking, fanged, flesh-eating white rabbit wearing a bow tie. Sounds like fun, doesn't it?
We haven't seen any of these critters yet in the main story, but they play a key role in the radio play Revenge of the Weasel Queen, when Agatha, Zeetha, Krosp and Othar Tryggvassen, Gentleman Adventurer show up at the town of Zoggletonk to Do Good and Slay Evil. This town has recently fallen afoul of the eponymous Evil Weasel Queen, Ferretina, who uses lapinemoths as muscle, although our heroes don't understand the connection immediately. Three of them are menacing the unconscious Jorf Oxclonker when Agatha, et al., and dispatch them in various creative ways.
This might be the end of the story in a normal, boring world, but in the Foglio-verse, things are never that simple. Othar, who's not the brightest bulb on the Christmas tree, draws a catastrophically mistaken about the young, oddly-dressed woman on the scene — none other than Ferretina herself — and soon puts himself in a position where he needs rescuing, from another, subterranean pack of lapinemoths among other things. Agatha and company figure this out, and Agatha that the way to invade Ferretina's lair and deal with her (maybe rescuing Othar if it's convenient...) is for the party to disguise themselves as 9-foot-tall, talking, fanged, flesh-eating white rabbits, tie optional. They just happen to have appropriate supplies of rabbitskin (lapin) laying around after doing their dispatching, what a coincidence! Agatha builds a Fashion Clank to do the haberdashing, although it has of how its creator and her friends should be attired, and is mortified to find out just what it was made for.
There are more lapinemoths in the emerging Revenge of the Weasel Queen, , so watch this space.
