The Giggling Fungus. Jitter Jumpers, #36

Eleven-year-old Lamont likes things neat, predictable, and, above all, not slimy. But his orderly life is upended when he discovers a fungal specimen that doesn't just grow; it communicates. Using "bio-resonant frequencies" to giggle at the world around it, the fungus is the key to a discovery by the eccentric Professor Finch. As Lamont is drawn into a "universe brimming with unimagined possibilities, " he must decide if he's willing to get his hands dirty to save a life that is literally out of this world.
