Season 4 Episode 29 : Season 4, Episode 29 - Oh Brother!
The Snorks are a race of small, colorful beings that live happily in the (saltwater) underwater world of Snorkland. They have snorkels on their heads, which are used to propel them swiftly through the water. As evidenced by the cartoon series, when a Snork becomes excited their tube makes a "snork" sound. They have much of the same technology as contemporary humans, adapted to their own aquatic environment. The Snorks use clams as currency ("clams" is also a slang term for money).
