What a Sponge!: Spongebob feels like he's not needed in Bikini Bottom anymore, so he leaves the town for good. Everyone (even Squidward and Plankton) starts to miss Spongebob and all the things he did to help them. They go on a hunt for Spongebob, led by Patrick, and finally track him down in New Kelp City, the city where he lost his memory and gave the freedom of blowing bubbles to the town. When asked why he moved here, he said everyone loves him here, because he's a hero, and back in Bikini Bottom, he's a loser. Patrick and the rest of the gang then say that Spongebob is the best person to ever live in Bikini Bottom, and give a rousing speech to persuade him to come back. Spongebob realizes that everyones does care for him, and decides to come back. Back in Bikini Bottom, Mr. Krabs holds a "We Love Spongebob" party at the Krusty Krab, that EVERYONE that appeared in the series attended. The episode ends with Spongebob sending out a message that everyone here are the best friends a sponge can have.

This episode is one-hour long and includes Patchy segments.
Patchy Story: Patchy celebrates Spongebob's 20th anniversary by throwing a huge party at his house. The only problem is, nobody showed up. Not even Spongebob, whom Patchy invited. Patchy thinks the invitations got lost in the mail, but Potty says that nobody even bothered to come because they didn't want to. Sad, Patchy decides to make his own party guests (a la Pinkie Pie in "Party of One"), and watch the special with them. At the end of the special, a bunch of people came to his party at the last minute, only for Patchy to say the special's over. One of the guests happens to be singer Anne-Marie, who sings an original song about everybody's favorite sea sponge. The special ends here.
