The episode begins with Dennis finishing up the last touches on his diorama about Egypt. As soon as he's finished, he shuts off the kitchen light and turns to walk away. Not a second after he turns away, a loud crash is heard in the kitchen. Dennis immediately checks to see what it is, and he sees The UG RV crashed through his kitchen. He looks over and sees Uncle Grandpa sitting next to his diorama, picking out pieces and eating them. This enrages Dennis, as he yells for Uncle Grandpa to stop. Uncle Grandpa does not understand what's wrong.

Dennis finally gives up and accepts that all his work is destroyed. He tells Uncle Grandpa how he's going to have to go to summer school, and his only chance of getting out of summer school was the diorama. Uncle Grandpa finally understands what's going on and offers to help Dennis get a new diorama. At first, Dennis is skeptical, but Uncle Grandpa reveals that he could get him an A+++++-+ in the class. Dennis decides he has nothing to lose and decides to go along with him.

Uncle Grandpa tells Dennis that he is going to get him a real Egyptian pyramid to bring to class. Belly Bag summons a sarcophagus elevator. After a bit of hesitation and thinking (and Dennis yelling at Uncle Grandpa to choose the correct button), Uncle Grandpa transports them to Egypt. Once in Egypt, Uncle Grandpa points out the pyramid Dennis will be taking home for the project. Since it's too big to carry on their own, Uncle Grandpa summons Mr. Gus, Pizza Steve, and Giant Realistic Flying Tiger to help them get the pyramid to Dennis's school.

They trek all around the world and finally get it back to Dennis's school. Unfortunately for Dennis, the pyramid is wrecked and it took one light touch from Uncle Grandpa to destroy it. This angers Dennis, but also makes him accept defeat even more as he walks to class with shame.

Dennis walks into Mrs. Numty's class and explains to her what happened and why he does not have the diorama. During his story, he reiterates what he knows of Egyptian culture, including the "Mummy's Curse". Mrs. Numty passes this story off as a "lame excuse". This reiteration of the curse, however, summons the mummy from within the broken pile of rubble that was once a pyramid. When Uncle Grandpa sees this, he deduces he can use the mummy to scare the teacher. Belly Bag reminds him that they can scare the teacher into giving Dennis an A+++++-+ in the class. Uncle Grandpa tells the mummy that he woke him up and has the mummy chase after him.

After a crazy chase within the school building, Uncle Grandpa makes it to Dennis's class. Uncle Grandpa greets the children and asks them if they like mummies. They all say "we do" and immediately the mummy bursts in ready to attack. Mrs. Numty cowers to the corner of the classroom scared for her life. She makes a deal with Dennis that if he can get rid of the mummy then he can pass her class. Uncle Grandpa helps Dennis defeat the mummy by eating up his wrappings like as if it were spaghetti. Once the mummy is gone, everyone cheers and Mrs. Numty awards Dennis with an A+++++-+ in her class. Dennis concludes that Uncle Grandpa's plan was to eat his diorama and take Dennis on an adventure so he could get that really awesome grade. Uncle Grandpa confirms it and makes a mummy pun that disappoints the entire class.
