Sandy comes down with a case of the blues and SpongeBob is determined to find out why and what he can do about it. The cure proves a little more challenging than expected when it turns out Sandy is homesick for 'good 'ol Texas' and plans to go back home. SpongeBob and friends decide to bring a little bit of Texas right to Bikini Bottom. The evil Plankton is up to no good once again when he tries to manipulate SpongeBob into becoming aggressive and mean in order to get more out of life. SpongeBob discovers that just because people obey you they don't necessarily respect you. Besides, it's just more fun to be nice to people and have them like you.
