弗林船长和恐龙海盗The Sea of Excitement is experiencing an unusually calm day, that is, until the Acorn runs aground on an island of stinking seaweed. Unable to get free, Tom invents a 'stinky seaweed sucker-upperer'. It works! That is, until it explodes causing stinky seaweed to spurt all over the Acorn and the crew. Captain Stubble sticks his head out of the galley porthole, sniffs the air, and announces the seaweed could be just the flavour he's been looking for, for his custard. As the kids sit down to dinner and sample the seaweed custard, some strange and silly side-effects soon become apparent. Pearl announces she's feeling light-headed and floats to the ceiling. Flinn tries to rescue her but has completely lost control of his legs. Violet grown a long beard which she keeps tripping over and Tom simply can't stop hiccupping. It's all an effect of the seaweed. Stubble declares he is unaffected, but soon his nose glows a bright green.
