Snotland is a small island of mostly sand and rocky spires. There are a few stubby trees, which Hookfang promptly incinerates.
During the events of "Cast Out, Part 1", Snotlout is grounded from flying and kicked out of the Academy, for making reckless decisions that negatively affect his teammates. In defiance, he flies away from Berk and lands on an island he dubs "Snotland". As he later finds out, he and Hookfang are not the only residents.
