Ep 12. Blackened Sponge/Mermaid Man vs. Sponge

While trying to wrestle open the cap off of a tube of toothpaste SpongeBob accidentally punches himself in the face leaving behind a hideous black eye. Too embarrassed to tell anyone the truth behind the shiner, SpongeBob makes up a tale about a fight with a giant thug. But unbeknownst to SpongeBob, the bully in his story really exists, and he is not happy about this fictitious rumor that's going around about him. Plankton has brainwashed Mermaid Man and Barnacle Boy! With the dynamic duo under Plankton's control, he orders them to wreak havoc on the Krusty Krab. It's up to SpongeBob SquarePants and his trusty spatula to save the day!
