I would say sinking it ALL is a bit extreme. Send a tsunami, sink a few islands, but the archipelago in all its entirety? Even Poseidon didn't sink the world when he got angry, he just sunk Atlantis (a teeny island)

Ah, yes, that's a good idea. I was thinking of it as all one landmass, rather than smaller islands. I might sink bits, then, depending on what Jet says

EDIT: All though you have to remember that Poseidon didn't WANT to drown the world, but Kraken does.
