One night in Bikini Bottom, a mysterious fog appears and the voices of mermaids are heard. That morning, SpongeBob realizes his alarm clock, Gary's shell, Squidward's clarinet, Patrick's cuff links, and Mr. Krabs is missing. While investigating, SpongeBob, Squidward, and Patrick are sucked into the triangle. They find Mr. Krabs, who tells them that he loves all the piles of "resellable stuff." He realizes that Pearl is left alone at the Krusty Krab with all his money, but she gets transported to the triangle too. Pearl and Squidward relax, Mr. Krabs looks for change, and SpongeBob and Patrick look for the mermaids. The mermaid quintet only knows how to "surround themselves with cool new stuff" whenever they feel like. They call SpongeBob's dilemma "TNOP" (totally not our problem). SpongeBob then quickly says upon return, "Unfortunately, I was unable to get the information from the aauugh," and being noticeably tired, he simply collapses. Mr. Krabs realizes SpongeBob desperately needs a Krabby Patty. He finds one and feeds it to SpongeBob. He then wonders who made the Krabby Patty. Mr. Krabs wants to go back when he thinks that Plankton might have stolen the formula. The whole group goes to the mermaids, and Pearl wants to go to the mall, and the mermaids want to go too. So the mermaids sing backwards. They get sucked back to Bikini Bottom. Pearl and the mermaids run to the mall while other people look into the pile to find all of their stuff. While the people are reclaiming their property, Mr. Krabs wants to see whether Plankton is actually trying to steal the formula again. He finds Charles who SpongeBob met earlier. It seemed that he caught Plankton trying to steal the formula. Patrick finds his cuff links and puts it on his tuxedo. He says to the driver "home reginald" and then steps inside the limo and drives off.
