The Sea of Teeth is a large green ocean that appears to be in a constant state of darkness as numerous storm clouds are always hovering over it. It is infested with numerous sea monsters of all kinds, ranging from sea serpents to even the mythical Kraken. Flapjack, K'nuckles, and Bubbie along with The Inventor of the Whoosh were the only ones to ever survive the sea's dangerous trials.it has a slight resemblance to the Sargasso Sea once feared by early sailors because of the algae and seaweed that often stopped boats in their tracks. The vicious Eight-Armed Willy resides here as well within a small undersea cave that is connected to the Stormalong laundromat.
