This volume has Spongebob and Patrick doing everything from replacing Mermaid Man and Barnacle Boy for a day, to getting in the wrestling ring to hosting King Neptune's 5,000th birthday.
The volume starts off with Spongebob becoming the richest person in Bikini Bottom when he finds a huge pearl. Spongebob quickly learns that his massive number of new friends don't stick around long when the money eventually dries up.
Mermaid Man and Barnacle Boy's first appearance in this volume occurs when Spongebob and Patrick find out their favorite heroes will be signing comic books. Unfortunately, it's happening the same day as one of Spongebob's Boating School classes. When he sneaks out by requesting a restroom-break, he is able to get the autograph. Instead of heading back to class, a series of events occur that keep Spongebob from going back. Everything about this day ends up going right, everyone at Goo Lagoon loves him, the jellyfish literally swim into his net and nothing seems to go wrong, that is, until he learns that one of Mrs. Puff's students turned to a life of crime after ditching class one day. Fearful of the path he, himself, might be starting down, Spongebob tries as hard as he can to return to school before the day is out.
The aquatic heroes make another appearance in "Shuffleboarding." Here, Spongebob and Patrick find out that the dynamic duo can't attend a shuffleboard contest, so they get permission to dress up as the pair in order to win the big prize. Instead of returning to Mermaid Man and Barnacle Boy's side after the game, Spongebob and Patrick decide to use their disguises as an opportunity to fight some crime. Needless to say, not everything goes as planned.
One episode I especially liked was "Grandpappy the Pirate" in which we learn that Mr. Krabs comes from a long line of pirates, and as far as his grandfather knows, the Krusty Krab is a pirate ship, not a restaurant. So when the peg-legged crab announces his visitation, Mr. Krabs has Patrick, Spongebob and Squidward redesign the fast-food joint to look like a pirate ship.
Plankton also makes a few appearances in this collection. One involves a fight he and his computer-wife Karen have when she demands he show her a token of love before revealing the Krabby Patty formula which she has just finished analyzing. Spongebob, not realizing the consequences of his actions, helps Plankton show his feelings to Karen.
In another episode, Plankton hires Patrick when he inadvertently creates an effective catch phrase for the Chum Bucket. The restaurant becomes so popular that the Krusty Krab loses a lot of business. A third Plankton-centric episode involves the single-celled villain learning that Mr. Krabs keeps his formula under the baseboards in his office. When Plankton starts drilling his way under the Krusty Krab, he discovers a massive chamber and uses the scenic location (and cave-dwellers as cheap labor) to increase his business. Once again, the Krusty Krab feels the loss of patrons, that is, until Mr. Krabs decides to do some digging and undercutting of his own.
The volume ends with a massive celebration as King Neptune turns 5,000. He decides to hold his birthday party at the Krusty Krab, but Spongebob soon realizes that the underwater monarch isn't all that happy. When he learns that Neptune's son, Triton, was banished many years ago for delving a bit too much in the matter of mortals, Spongebob decides to track down Triton and get him to his Dad's birthday party.
Spongebob Squarepants: Season 6, Volume 2 also comes with a few special features like a song-and-dance number put to the Spongebob theme called "Bollywood Bob." There is also a short featurette on how to make your own Spongebob Squarepants with a yellow sponge, some pipe cleaners and construction paper. There are also two shorts that accompany "The Clash of the Triton." One is about what Spongebob would do if he were a god and the other is the about the origins of King Neptune.
All-in-all, Season 6, Volume 2 has enough good episodes to warrant picking this DVD up for any Spongebob fan. Given the nature of the show, there isn't any requirement to owning or knowing details about the past seasons, so even if you haven't started your Spongebob collection yet, but know you really like the yellow guy, this isn't a bad place to start.
