Armstrong Wedgewood (Matt Lucas) celebrates the ugly and unconventional killers of the deep; from hospitablesea cucumbers to predatory starfish and deadly molluscs. Wedgewood feels a strong affinity with the ocean's "backroom boys" who play a vital role in maintaining the delicate balance of the oceans' ecosystem. Armstrong is also keen to promote a certain cruise line, much to thechagrin of his long suffering producer.
