When things start going missing on Sealab, fingers start to point and tempers start to flare. It'll be up to Murphy and his cadre of Martian Knights to quell the chaos. Or, more accurately, to exacerbate the existing chaos into something much more chaotic. But at the end there might be cake.
In a fevered spurt of conspicuous consumption, Murphy runs up a hundred grand in credit card bills. And let's face it: He just doesn't have that kind of money. So he sends his unwilling crew in search of sunken treasure. Sharks? Sure. Lack of oxygen? You bet. And hey, isn't that dynamite over there? Well, I'll be darn.
Adorable-ness ensues when Murphy buys a cute little Gloop from a sexy Asian lady. But what the...? Those things are multiplying like crazy! And they've got a hankering for the kelp harvest! And they're filled with poison gas! And we better get some flamethrowers down here to show those damn Gloops who's boss!
Murphy and the Sealab crew are held captive... by the Bizarros!
Well, a summary of this episode would, in its essence, be a spoiler. But get ready to see some of your old favorites (and some soon-to-be favorites) in this season finale: Chopper Dave. The Bebop Cola Robot. The Forest Ranger Guy. Skanky Darlene. The Martian Quinn. And who can forget Debbie's boobies?
