Big Blue is a Canadian animated television series for children ages 5 to 9 created by Gyimah Gariba and produced by Guru Studio.

[4] 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.

Note: The Blegh and Bacon Berry are the only characters to pass away, which was both at the same time in this episode, so this was shown emotional to viewers upon seeing BB’s sacrifice.
