Frightfully friendly ghosties

Tabitha Tumbly, Charlie Vapor, Rusty Chains, and their friends can't understand why the still-alives in their house are so mean. The friendlier the ghosties are, the meaner the still-alives become! When the still-alive family puts garlic around the house and calls in a priest, Tabitha and Charlie decide to invite The Ghoul to sort out the still-alives once and for all. But could the terrifying Ghoul prove to be more trouble than the ghosties bargained for?
