Dina promises everyone that she will get Jamie Mallet Jr., a huge rock star, to perform at the camp dance. She finds out that Jamie is staying at a nearby camp to relax and get some rest from the celebrity lifestyle. Dina tricks him into thinking the camp he is at is too dangerous and to come and relax at Camp Anawanna. When he arrives, he is overrun by fans. Dina then gets angry when Jamie spends most of his time hanging out with Pinskey instead of her, because Pinskey isn't treating him like a celebrity. As revenge, she spreads lies about Jamie through the camp.

The girls decide that they want to be away from each other, so they ask Ug to change the bunk assignments. Meanwhile, the boys find a buffalo skull in a cave near camp.

After sleeping through the camp's Club Choice Day, Pinskey ends up in Sponge's computer club. He then decides to use the camp's outside modem line to make long distance phone calls.

Donkeylips wants to play on the offensive side of the camp's Capture the Flag team, but even though he knows the strategy, he is put on defense because he is so slow. But when the offensive crew is captured by the enemy, it is up to Donkeylips to lead the defense team to save the day.

Mona Tibbs, the mail lady, has joined the park service to be closer to Ug. He thinks this is good because she will go easy on the camp when she comes to inspect it. Instead, she nitpicks every little thing and reports the camp for several infractions. The campers decide to make it worse by pointing out more flaws, hoping to be put in a hotel while the camp is fixed if it is shut down. They find out, however, that they would be transferred to other camps. They quickly set out to clean up camp and help Mona and Ug patch things up.

Ellen, Dr. Kahn's niece, comes to visit camp, and Ug orders the campers to treat her like royalty.

The group must put on the camp's presentation of Cinderella. Dina is cast as Cinderella with Michael as the prince. Telly must play an ugly step-sister and Donkeylips is the coachman.

After Ug breaks up with his girlfriend, he starts to crack down on the kids for every little rule violation. When a new mail carrier named Mona shows up and seems to take an interest in Ug, the kids try to get them together, thinking that he will ease up on them if he starts to go out with her.

Z.Z. tires to get the others to clean up the camp. Unfortunately they really don't care. So Dina helps her throw a party to try and raise awareness, but that just makes a bigger mess.

After Michael accidentally ruins some brownies that belonged to the camp's meanest kid, Thud Mackie, he needs to do something or face a beating.

As the groups try to be the first to the treasure, Donkeylips and Budnick find that watching the hunt is hillarious.

In order to get out of the daily activties, Michael and Budnick fake being sick. They end up spemding the day in the nurse's station with no good food (the fridge has ice cream in it, but is locked), and watching spanish TV. Meanwhile, the day's activity, unknown to Michael and Budnick when they faked ill, is a trip to the beach. The others look forward to a day of fun in the sun, but Ug decides to put Z.Z. incharge of the map and they all get lost.

In order to win a lobster dinner, Sponge and Donkeylips enter the wrestling tournament. Unfortunately Sponge is too light to wrestle and Donkeylips is too heavy.

In order to win the grand prize, $1000, he must stay awake for 24 hours and wait for a phone call from the DJ and answer more questions. In exchange for a cut of the prize money, the others help to keep Sponge awake, sneak him past Ug to the phone, and force him to study for the questions.
