Maddie welcomes the viewers and says it's time to make a silly craft. She and the Peanut Gallery are making paper plate hippos. Then it's time for Peanut Gallery Sleepydunes. Meanwhile, Peter, Duck's Brother, is watching Happy Hippos, when Duck turns it off because he wants to watch Gross Class Zero. Peter says he got the new Happy Hippos Super Duper Bumper Wumper Happy Tastic Hippo Hippo Hooray Box set for being so good at the dentist. Then Sayje tells him that the Happy Hippos are having their 40,00th episode celebration, and he and Peter and inVited. There, the Happy Hippos show a flashback of them with a group of children called the Hippoketeers (Maddison, Macrae, Gabriel, Brad, Aspen, Sierra, Madeline, and Mia) - parodies of the Mickey Mouse Club. Hippoketeers Maddison, Macrae, Aspen, and Brad have a reunion at the 40,00th episode party. Then the Male Hippo says that they will have auditions for new Hippoketeers. Kids try out. Then the other Male Hippo says that the Hippoketeers chosen are Robert, Caroline, Peter, Gordon, James, Maggie, Dakota, Dylan, and Gabrielle. After the auditions, Sayje and Duck find a Gross Class Zero DVD. Then Duck tells Peter about a Happy Hippo parade. Peter changes into his happy hippo costume and Hippoketeer hat he got at Happy Hippo World in Orlando. Then Duck begins to bring the TV and the DVD player upstairs but falls down. Duck's parents ask what is going on and Peter says "Duck was taking the TV and DVD player upstairs (although it was my turn), and he told me there was a Happy Hippo parade outside, and I waited and waited in my Happy Hippo costume, but there wasn't one" Duck goes to Weehawken School and asks Mr. Nitch to show Gross Class Zero to the Nitchers. Andrea wants him to "pass around the popcorn", which is right next to her. Duck puts his Gross Class Zero DVD on, and says "At last, Gross Class - Hippos?" and a Hippo (voiced by Duck Alivia) says "Are you ready for some super duper happy tastic hippo fun?" and Mr. Nitch says "What do you say you have Gross Class Zero, when you really wanted to watch Happy Hippos, just like a Baby" and Duck worries he messed up the DVDs. The Nitchers start singing the Happy Hippos theme song. His dad tells Duck that he has a Gross Class Zero video from the Library but Mom says it's way past his bedtime. Duck screams and the episode ends.
