Big Blue is a Canadian animated television series for children ages 5 to 9 created by Gyimah Gariba and produced by Guru Studio. The series debuted on CBC Kids on December 4, 2021, in Canada, on Nicktoons on January 10, 2022, in the United Kingdom and on The Roku Channel on October 1, 2024, in the United States. The series follows Lettie, and her crew as the Calypso in United Current, with her brother, Lemo, pals Freddie and Phil and Bacon Berry, who might just be the one who can save the Big Blue. They go on missions and explore the ocean and must stop the splat of pollution, the Blegh, who can only be defeated by Bacon Berry, and discover why and how they can care for each other around any predicament.
Set in an underwater world where humans live alongside anthropomorphic sea creatures, the show is about the crew of the United Current submarine Calypso, composed of the Sibling Team Lettie and Lemo (who are the crew's captain and science officer, respectively), a laidback turtle named Freddie (the ship's mechanic), a nervous dolphin named Phil (the resident medic), and Bacon Berry, a childlike magical guardian of mysterious origin and power. Under the command of the diminutive Admiral Krill and his number two Commander Plink, they explore the seas and take on missions to defend the ocean from various threats, most prominently a sapient mass of pollution known as The Blegh that seeks to corrupt all of the Big Blue, while helping to redefine what a family means and how caring for one another is the most important thing of all.
