The episode begins at the Krusty Krab, Sandals is trying to decide what to order. He decides to order coral bits, after SpongeBob suggests it, for one dollar, then an alarm suddenly blares out. Squidward assures the customer that "It's something stupid," and Mr. Krabs bursts out of his office and starts to dance with the recently obtained dollar in his hand to intense celebratory music. Mr. Krabs informs everyone that he has received his millionth dollar, which is every crab's goal in life. He kicks out all of the customers for "spoiling his moment," not even giving Sandals his coral bits, and tells SpongeBob and Squidward that they are going on a surprise trip to celebrate. Squidward asks if they are going to Fancy Springs, Pamper Island, or perhaps Bikini Bottom Folk Village, but Mr. Krabs states it is better than that.
It is then revealed that the three of them are going clam fishing on a cheap boat named the S.S. Cheapskate on a smelly lagoon, much to Squidward's disappointment. SpongeBob accidentally removes everything from the boat while he is casting his line, as well as Squidward's shirt and nose, which Mr. Krabs doesn't mind, until SpongeBob's cast hooks onto the back of Mr. Krabs' pants, which he foolishly taped his millionth dollar to, and rips it off. Once the dollar is thrown into the lagoon, dramatic music begins playing, signaling an incoming clam attack, and SpongeBob begins reeling in the dollar as quickly as he can. Mr. Krabs locates the source of the dramatic music: a live-action orchestra playing behind a wooden door. Mr. Krabs yells and begs for them to stop playing, but to no avail. SpongeBob manages to reel it into the boat, and Mr. Krabs grabs the dollar. However, a blue-lipped clam suddenly jumps out of the lagoon, grabs the dollar out of Mr. Krabs' claw, and falls back into the lagoon and swims away. Mr. Krabs childishly wails over this. This continues until Squidward, out of annoyance, states they will help Mr. Krabs get his dollar back. Mr. Krabs is happy to hear this and gives everyone supplies so that they can prepare themselves for catching the clam. Mr. Krabs then starts keeping a lookout for the clam.
"The Team," consisting of SpongeBob, Squidward, and Mr. Krabs, works for three days, but the clam does not come back. SpongeBob and Squidward have now become tired of waiting for the clam to come, so they attempt to make Mr. Krabs happy by giving him a dollar out of Squidward's wallet. It works at first, but after Mr. Krabs rubs the dollar on his butt like a towel, he becomes suspicious and figures out that it is not his millionth dollar, but an ordinary dollar that was crumpled up, torn slightly, soaked in the lagoon, and kissed with Coral Blue #2 semi-gloss lipstick, with Squidward bonking SpongeBob on the head before the latter reveals what the actual number of lipstick was. Mr. Krabs cries again, but Squidward tells him tears won't work this time, so he then nails a sandwich to a flagpole and states that the sandwich will be the reward for the person who can retrieve his dollar from the giant blue-lipped clam. He then tosses all the other sandwiches overboard to make it "the sandwich." Squidward does not care, saying that they have plenty more to eat, but he is interrupted by Mr. Krabs dropping the whole fridge overboard. Squidward, and eventually, SpongeBob, now realize that Mr. Krabs has become insane, so Squidward whispers to SpongeBob that they should sneak over to the lifeboat quietly while Mr. Krabs is not looking. However, they run for their lives to the lifeboat while screaming. Upon entering the lifeboat, Mr. Krabs is revealed to have been secretly inside.
He then throws SpongeBob and Squidward out while they are tied together. Mr. Krabs is angry that his own crew would betray him, so he makes SpongeBob and Squidward into live bait by hooking them to his rod. Squidward tells him the clam won't come until Krabs appears in a conductor's outfit. Soon enough, the dramatic music begins playing again with Krabs being the conductor, and this begins to freak them out. The blue-lipped clam begins swimming toward the boat. Soon enough, the clam opens its mouth and it is then revealed that the dollar is lying on its tongue. Mr. Krabs closes the sliding doors to stop the music, causing the clam to stop moving, so he jumps onto the clam's tongue, grabs the dollar and dances with it. However, the doors open back up and the dramatic music returns, causing the clam to shut its mouth while Mr. Krabs is still in it. The clam then dives back into the lagoon.
Thinking that Mr. Krabs is dead, SpongeBob and Squidward start crying until he is seen at the surface of the lagoon with his dollar. Mr. Krabs reveals that he and the clam fought until they made a trade. SpongeBob asks what he gave the blue-lipped clam, and Mr. Krabs hops onto the boat to reveal that he gave his whole body to the clam, except his head and arm, though he claims that he gave away nothing important, as the episode ends.
In the storyboard featured on the SpongeGuard on Duty DVD, after Mr. Krabs gets his 1,000,000th dollar at the Krusty Krab, he uses the restaurant's phone to call his parents Victor Krabs and Betsy Krabs at the Bikini Bottom Graveyard to tell them about it. The reason this scene was cut from the final episode is unknown.
