I passed up a chance to buy them and instead bought the Wreck Raider and Monster Crab Attack Atlantis sets.

I like them both. The crab has cool posable legs and the Raider is fun to swoosh.

I think the Atlantic keys would make good wheels on some wizard's cart of tricks. And also talismans for 9 MOCs.

Sharky is cute. :3

Also it's cool to have harpoon gun and grappling hook pieces now, as I'd never gotten any before.
