'SpongeBob Squarepants' and 'Planet Earth' Team Up To Teach Us About Plankton

The BBC's Planet Earth and SpongeBob Squarepants have teamed up for a nifty little video where they explained a vital living creature whose existence we may have taken for granted. As one of the show's characters pointed out, "If you're looking for the most important creatures on the planet, well here we are. Plankton! Do you doubt me? Sheldon J. Plankton?" Mr. Plankton pointed out, "All fish eat us. Bigger fish eat them all the way up the food chain...What this means is no plankton, no sea life. No Crabby Patties. No sushi. No SpongeBob. That wouldn't be so bad."
