Brady puts Ember and Virgil on monster watch during his short trip out of town. A mysterious creature has arrived in Ravenville, and its smell is so toxic it is creating havoc around town, knocking people and monsters unconscious, melting cars, etc... Ember and Virgil finally track and meet the charming, elegant but smelly Stinker. They try everything (bubble baths, fire hose rinse, fountain dip, etc.) to wash the stink off, but to no avail. Luckily Brady returns from his trip and shows them the only way to neutralize the harmful fumes. The source of the stink is internal and emotional. They must make the Stinker feel good about himself, and sure enough the smell is gone, making it easier for everyone in Ravenville to enjoy their new friend – the Stinker.
