Are you stuck on beating Seabed Shanty in under 1:20.00 like I had been for six years? Well, here is how you do it. After the N, swim to the right, past a bunch of Lurchins, until you reach a wall. Swim in the corner of the wall, and you will find this invisible barrel cannon that will launch you through the wall, saving you lots of time! This barrel is so obscure... hopefully this helps people!
