The Grotto is an underground area in Postal III.
Champ Rescue Edit
After walking around in the Krotchy suit for awhile, the Postal Dude stumbles on a trail left by Champ. Ditching the Krotchy suit, the Postal Dude follows the trail underground where he finds Al selling the freed animals from Evolusious Cosmetics to the Mexi-Sushi concern. Not happy about this, Champ decided to rescue his captured animal friends and take a bite out of crime.
