SpongeBob SpongeBash (8 p.m., Nickelodeon): The 10th anniversary of our undersea cartoon hero with the square pants is being celebrated with a weekend marathon of episodes that even Patchy the Pirate would enjoy.

It’s a chance to see Miley Cyrus share the screen with Selena Gomez and Cole and Dylan Sprouse.
