Nobody wants to adopt the Shluffmuffin twins. Wally's feet stink something awful, and Cheyenne is allergic to everything. Then why are the Mandible sisters so eager to take them home? And what sort of old maids would choose to live in a place called Dripping Fang Forest, where zombies wander the woods singing "Itsy Bitsy Spider" and ten-foot-long glowing slugs want to suck the feet right off your ankles? Would it seem ungrateful of Wally to point out the Mandible sisters' extra arms? Or to question their all-chocolate, all-the-time menu? Or, um, to venture into the cellar, where the twins have been told to NEVER, EVER, EVER go? Yeah, perhaps that last bit was a mistake. Now there's nothing left for the Shluffmuffins to do but run—run for their lives!
