Why on Earth did they do this? This is one of the worst SpongeBob episodes, oh I'm sorry, "TV movie", eesh! The songs are so terrible and the plot was completly stupid. David Bowie's guest appearance didn't make it any better. The animation of the Atlantis citizens is so repulsive and disturbing. And the Patchy the Pirate sequences are so cheap. Has Stephen Hillenburg ever heard of visual effects? Hillenburg really needs to get rid of the Patchy the Pirate character.
If one of your life goals are to watch every SpongeBob episode ever made, you can pass on this one.
