Mutated sea-creatures are being discovered at a rising rate, and the Planeteers set out to learn why - but Gi and the others are unaware that in her anger of putting up with Suchi while enhancing the Ecosub's controls, she lost a gear for the speed-increasing control. They only find this out after they've already taken off to investigate the water-contamination that is the result of Sly Sludge's illegally pouring waste in the ocean. Things get out of hand when he sees them before they see him, so takes a reporter and young fisherman aware of the crisis as hostages in case his old enemies return. But the Planeteers have their own problems to deal with, like escaping a large clam that accidentally traps them when the sub crashes through Sludge's barge, and still have to get out in time to stop a large mutant squid from attacking a sea-coast.

Give me a break. We're gonna try to tickle the clam open? Is that the best you can do?
Yes. It's the best shot we've got. Matter of fact, it's the only shot we've got.
Shouldn't we think about this a little more?
Clam up, Wheeler.
