It was night time. In the lounge, Mundy's parents were talking to Mundy.
Mundy's dad: Conrad, we are going to the Great Wolf Lodge to stay overnight, but you're not coming. Because we can't trust you to behave there.
Mundy was shocked and offended.
Mundy: What? I can't come? I cannot believe you are leaving me behind all alone! You guys are so unfair!
Mundy's parents were stern.
Mundy's mum: Well, guess what? Your behaviour is really rude and disrespectful.
Mundy's dad: I agree with your mum, you have failed to behave every single day.
Then Mundy's parents stopped glaring, and his dad began to offer Mundy a deal.
Mundy's mum: But I'll tell you what. If you behave by the time we get back, you'll come back with us next week and you'll be ungrounded, okay? See you tomorrow!
Then Mundy's parents walked away from Mundy.
Mundy's mum: And make sure you don't do anything stupid while we're gone.
Then Mundy thought for a minute.
Mundy: Now that they are gone! I am going to invite my friends for a slumber party!
Then Mundy walked out of the lounge to call all of his friends for a slumber party.
Skeens was in his bed, and then he heard his phone ringing. Then he lifted himself up from his bed, and started to answer the phone.
Skeens: Who is this?
Mundy was in the kitchen, and he was talking to Skeens on the phone.
Mundy: Hello Skeens! This is Mundy! I am inviting you over for a slumber party! Wanna come?
Skeens: A slumber party? Oh boy! My parents are at the Great Wolf Lodge, so I'll be on my way!
Twenty minutes later, Mundy had invited all of his friends Skeens, Lazy Kid, Sue Bob Murphy, Lawson, Gelman, Clyde Philmore, Kurst the Worst, Chucko Kowalski, Cy Kowalski, Jocko, Koreo, Buster and Cheay and brought them in the lounge.
Mundy: Now that you are all here, let's start the party!
Then Mundy turned on the radio and the music of Let's Dance started playing. The whole house was shaking. Meanwhile in Principal Prickly's house, Principal Prickly was chatting with Miss Finster, Miss Lemon, Superintendent Skinner and Coach Kluge.
Principal Prickly: So I'm like... yeah, a donut must have a whole lot of sweetness inside it.
Then everyone laughed, and then suddenly they heard the whole music coming from Mundy's house. Loud music shattered the glasses of Principal Prickly's house.
Principal Prickly: Holy shnugget! I better check what is going on out there!
Then Principal Prickly looked out of the window, and then he looked annoyed.
Principal Prickly: Just as I suspected. Guys, Mundy is having a slumber party when he's not supposed to. We got to get over there and stop him once and for all! Let's go!
Back in Mundy's house, Mundy and his friends kept on dancing, and then suddenly, Principal Prickly, Miss Finster, Miss Lemon, Superintendent Skinner and Coach Kluge burst in, and Principal Prickly turned off the radio, much to Mundy and his friends' shock.
Principal Prickly: There you all are! You're all are in so much trouble! We're calling your parents!
Mundy: Quick! Get the melatonin spray!
Then Mundy and his friends got the melatonin spray, and they aimed at Principal Prickly, Miss Finster, Miss Lemon, Superintendent Skinner and Coach Kluge.
Principal Prickly: Wait! What?!
Then Mundy and his friends sprayed Principal Prickly, Miss Finster, Miss Lemon, Superintendent Skinner and Coach Kluge with the melatonin spray, which sent them to sleep. The next morning, Principal Prickly, Miss Finster, Miss Lemon, Superintendent Skinner and Coach Kluge were in Mundy's basement, Principal Prickly and Miss Finster were sleeping on the floor, Coach Kluge was sleeping in front of the wall, and Miss Lemon and Superintendent Skinner were sleeping upside-down. Then Principal Prickly, Miss Finster, Miss Lemon, Superintendent Skinner and Coach Kluge woke up.
Principal Prickly: Hey, where are we?
Coach Kluge picked himself up.
Miss Finster: Uck! Why am I sleeping on my breasts?
Then Miss Lemon turned herself right-side-up.
Miss Lemon: Ooh, why is the world upside-down all of the sudden?
Then Superintendent Skinner fell to the floor.
Superintendent Skinner: Woah!
Then Superintendent Skinner landed to the floor.
Superintendent Skinner: Ouch!
Principal Prickly: I smell pancakes! I think we are in Mundy's basement!
Then Principal Prickly, Miss Finster, Miss Lemon, Superintendent Skinner and Coach Kluge looked crafty.
Principal Prickly: Wait a minute! I still have my cellphone! I can call Mundy's parents and he will be grounded!
Then Principal Prickly picked up his cellphone and started to call Mundy's parents.
Principal Prickly: Hello, Mundy's parents! This is Peter Prickly, principal of Third Street School speaking! Your son invited people over for a slumber party. Not only that, he locked me, Miss Finster, Miss Lemon, Superintendent Skinner and Coach Kluge in the basement. Please ground him! Alright! Thanks! Bye!
Then Principal Prickly put down his cellphone.
Principal Prickly: Don't worry, they said that they are coming home to ground the troublemaker and they'll free us from the basement.
Back in the lounge, Mundy and his friends felt satisfied.
Mundy: The sleepover and pancakes were good! But the fun is getting started!
Then suddenly, a mob of parents arrived, including Mundy's parents. They were furious.
Mundy: Oh no! We're busted!
Mundy's dad: Conrad!
Skeens' dad: Skeens!
Lawson's dad: Erwin!
Gelman's dad: Gelman!
Lazy Kid's dad: Richard!
Sue Bob's dad: Sue Bob!
Clyde's dad: Clyde!
Kurst's dad: Kirsten!
Chucko and Cy's dad: Chucko! Cy!
Jocko's dad: Jocko!
Koreo's dad: Koreo!
Buster's dad: Buster!
Cheay's dad: Cheay!
Mundy's dad: Why the heck did you invite all of those people for a slumber party! That's it, everybody go home while we deal with Conrad!
Then all of Mundy's friend went home in disgrace. Then Mundy's parents approached Mundy.
Mundy's dad: Katie, help Principal Prickly and the rest out of the basement while I deal with Conrad.
Then Mundy's mum went off to help Principal Prickly, Miss Finster, Miss Lemon, Superintendent Skinner and Coach Kluge out of the basement. Mundy's dad scolded Mundy.
Mundy's dad: Conrad, you know that you're not supposed to be having a slumber party! Besides, you were grounded!
Mundy: But dad! I wanted to have the most epic time of my life!
Mundy's dad: Well, guess what? We were going to let you go to the Great Wolf Lodge next week. But you lost your privilege to go there, we were having so much fun until you were having a slumber party. You're grounded, grounded, grounded, grounded, grounded, grounded, grounded, grounded, grounded, grounded, grounded! You're grounded for two weeks! Go upstairs to your room right now!
Then Mundy went up to his room, crying.
