Look out for the ghost goo! Dripping sticky green slime wherever it goes, and “ASG” (that’s Averagely Spooky Ghost) is hiding out in Tom’s cellar. Why? Because it’s being haunted, too- by a much bigger, way badder Incredibly Revolting Ghost (“IRG,” for anyne new to ghouls). And the IRG is the kind of ghost that uses its head- as a ginormous bellowing bowling ball, gross! Good thing for Tom his grandma’s best friend just happens to be a world-famous ghosthunter…

Boy hero Tom, Hugo the Averagely Spooky Ghost, and famed ghoul hunter Hetty Hyssop have formed an agency dedicated to dealing with difficult apparitions. No spook can defeat them-until their too close encounter with a Gruesome Invincible Lightning Ghost.

This superheated specter (or “GILIG,” in ghosthunter-speak) has taken over the penthouse suite of a beachfront hotel, where it’s passing its eternal vacation by turning guests into ghosts themselves!

Maybe Hugo’s slime can douse the flaming phantom- or maybe the ghosthunters’ plan is doomed to go up in smoke…

Get scared silly!
