Plankton are responsible for 50% of earth’s oxygen. They are an essential part of the food chain. And billions of billions of ancient plankton have given their bodies to form the crude oil that powers modern society.

Yet we rarely recognise their contribution to life on this planet, including our own.

So to celebrate all things planktonic, BBC Earth has partnered with Nickelodeon’s SpongeBob SquarePants and his arch nemesis Sheldon J Plankton to create this short film.

Watch, enjoy, and if you can find it within yourself, say a little thank you to what are perhaps the most important creatures on earth.
