Sherman

He's a happy-go-lucky shark who might share a popsicle with you one day and eat you the next. Being a great white shark, Sherman's hardware is daunting, however his software was never properly installed. The other Lagoonies take comfort in the fact that whatever intelligence he does possess is completely negated by his laziness. The only person Sherman manages to outsmart consistently is Captain Quigley, a crusty old fisherman who would give anything to see him stuffed, mounted, and hanging in a Red Lobster.

Megan

Inside that ruthless, man-eating exterior is a demure, nurturing woman trying to get out. Megan keeps her husband, Sherman, on a short leash.

Fillmore the Sea Turtle

Sherman's pensive sidekick provides the anchor of sensibility for an otherwise eccentric cast. Not that Fillmore is a normal, well adjusted sea turtle; far from it. He's bookish and slightly pompous, however he's sensitive and principled, and right most of the time.

Ernest

Like a brilliant brain surgeon turned to safe cracking, Ernest channels his precocious intellect towards nefarious ends. Ernest is an inspiration to all nerds who have grown tired of video games and yearn for a more fulfilling level of destruction.

Bob the Bottom Dweller

Bob feeds on garbage, small anchors, hand guns, and other assorted items that sink to the bottom. His tongue is always hanging out, his bug eyes are never quite lined up, and he communicates exclusively in burps and grunts.

Hawthorne the Hermit Crab

Size and attitude are oftentimes inversely proportional as the laptop crab with the mainframe disposition demonstrates time and time again. He's a toe-pinching, penny-pinching, party pooping, macho, beer can-dwelling, woke-up-on-the-wrong-side-of-life hermit crab who's a little too much crab and not enough hermit, thank you very much.

Captain Quigley

The crusty peg-legged sea captain has an endless supply of elaborate traps to unleash against the Great White Shark but the beast continues to elude him. Years ago, Quigley lost a leg to Sherman (there's no free lunch) and now he's determined to exact his revenge.

Thorton the Polar Bear

He's the polar bear who's perpetually on vacation. Ever since Thornton floated into the lagoon on a stray iceberg a few winters ago he realized that life on the tundra is not all it's cracked up to be. He now spends all his winters on Kapupu Island where he lies on the beach reading Tom Clancy novels and sipping frozen fruit drinks.
