"Uh, once upon a time..." she began. "Not that book." He points behind (Y/n). "That book." He said. The trio turn to see a book that is being held up by skeleton hands and is engulfed in flames. "I'm not sure that's a good idea." Mordecai said. "It is a terrific idea." Thomas said. "To you, maybe." (Y/n) said. "Just read it, bros!" Muscle Man begins to sweat. "It's starting to smell like B.O. in here for some reason!" He said. (Y/n), Mordecai, Rigby, and Thomas sit on the couch. (Y/n) is getting ready to read Thomas the story. "The Hungry Hungry Soul-Sucking Death Worm. Lovely."
She adds to herself sarcastically, and her best friends snicker a little. She continues reading. "The hungry, hungry soul-sucking death worm was so, so hungry-" she said. "Pull the tab!" (Y/n) pulls the tab. "He searched far and wide for souls to eat, but only got hungrier. Wow, this is garbage. You actually like this?" (Y/n) asked skeptically. "This is the most boring part of the book. It gets much better." Thomas replied. (Y/n) is now almost done reading the book. "And once all the souls were eaten, he took a nice, long nap. The end." (Y/n) looks up.
"Well, I'm officially scarred for life." She said. "No, wait. You forgot to pull the last tab." Thomas said. "Uh..." (Y/n) said. "PULL IT! This is my favorite part!" Thomas shouted. "Okay, okay! Chill, dude." (Y/n) said. (Y/n) pulls the tab, releasing a real life soul-sucking death worm, which breaks the table in front of them. (Y/n), Mordecai and Rigby scream and run away while Thomas claps. "Don't be afraid, just feed it!" He said. "What do we feed it?" Mordecai asked.
"Souls." He tries to teleport Muscle Man out of the amulet. "Wah!" The death worm roars happily when it sees Muscle Man. Rigby screams in fear and runs away with (Y/n) and Mordecai as the hungry creature comes towards him. He keeps running and turns around only to see the death worm right behind him. He quickly thinks of an idea and takes off the amulet. "(Y/n), catch!" Rigby throws the amulet and barely avoids getting bitten by the death worm. Muscle Man screams as he is hurled through the air. (Y/n) manages to catch the amulet, which makes the death worm start to chase after her instead.
As it turns, its tail hits Rigby in the face, causing Rigby to be flung into a TV. "Rigby!" (Y/n) shouted. "What are you doing? Give it the fat man's soul!" Thomas shouted. "Never!" (Y/n) shouted. He climbs up (Y/n) in an attempt to get the amulet. "Hey! Uuuuh!" Thomas bites (Y'/n)'s arm, causing her to drop the amulet. "Ow!" "(Y/n)!" Mordecai shouted worriedly. "Leave her alone!" The amulet rolls away. "Augh, knock it off you little demon!" She shouted furiously. The death worm smiles as it sees Muscle Man, and Thomas laughs with glee. Before Muscle Man can be eaten, however, Rigby rolls by and snatches up the amulet. "Got it!" Rigby said. "Watch out!" (Y/n) shouted. Rigby rolls out of the way right before the death worm eats him.
"A little help, guys?!" Rigby asked. Mordecai and (Y/n) run to catch up with Rigby. "Dudes, we have to get the worm back in the book!" Mordecai said. Rigby tosses the amulet. "Take Muscle Man. I got a plan!" He runs away. "Rigby!" Mordecai and (Y/n) shouted. Rigby slides into the living room and grabs the book. Meanwhile, Mordecai and (Y/n) are running away from the death worm as Thomas follows in hot pursuit, laughing. Mordecai and (Y/n) then run up a flight of stairs, causing the death worm to chase them. "No, no, no! This is not how it is written! The worm must eat the soul!" He throws a piece of wood at Mordecai and (Y/n).
They both duck. "No way, you bloodthirsty little jerk!" Mordecai shouted. They continue to run away as the death worm appears right behind them. Rigby then runs back into the room with the book in his hands. "Mordecai, throw Muscle Man over to Thomas!" Rigby said. "What?!" (Y/n) asked. Mordecai and (Y/n) are running up the flight of stairs again. They stop when they hear Rigby say this. "He'll just feed him to the worm! " Mordecai shouted. The worm roars in response. "Trust me!" Rigby shouted. "You better not do it, man!" Muscle Man shouted.
"Sorry, Muscle Man!" He throws the amulet over to Thomas, which confuses the death worm. Muscle Man screams in anguish. "I will feed it myself if I need to!" Thomas! shouted. The amulet lands into his open hands. "Huh?" The death worm then proceeds to jump down the flight of stairs in order to get to Muscle Man. "Ah! That's not what I meant!" Right before the death worm can eat Muscle Man's soul, Rigby jumps in front of Thomas with the open book. Rigby screams as the death worm starts to get sucked back into the book, and (Y/n) picks up Thomas and the amulet. The death worm has its tail wrapped around a chandelier, but that does not stop it from getting pulled back into the book. Rigby then closes the book in success.
"Dude. Nice!" Mordecai said. "You did it!" (Y/n) said with relief. "Thanks!" Rigby said, who's face has been messed up from the force of the worm getting sucked back into the book. "Ugh. I think I'm gonna hurl." Muscle Man said. "Augh! That was an awful storytime!" Thomas shouted. "Hey, we read you the story, now go to sleep!" (Y/n) shouted furiously. "I could have been killed! I'm never going to sleep! Never, ever! Look at the time!" The trio look at the clock which shows that it is almost eight p.m. and they gasp. "Mommy and daddy will be back any minute now, and when they see me wide awake, they'll go ballistic."
Footsteps are heard right outside the door. (Y/n), Mordecai and Rigby gasp in fear. Thomas starts laughing, only to be silenced when the chandelier falls on top of him. (Y/n), Mordecai and Rigby grimace. "Dudes, we're so dead." Mordecai said. "Uh huh." (Y/n) agreed. "He could... be alright." Rigby said hopefully, then the door opens. "We're back!" Death gasps. "Oh! What happened here?" Death walks around and points out everything. "Broken furniture all over the place? Fires everywhere! My favorite harp: ruined! Unbelievable!" He walks back over to (Y/n), Mordecai and Rigby and is furious with them for the destruction of his house.
"And what about Thomas?!" He asked. "Uhhhhh...." Rigby said. "Thomas?" Death's wife lifts up the chandelier. "He's out cold." She walks back over to Death. "Oh, thanks for a perfect anniversary, darling." She kisses Death and walks away with Thomas. "Right." Death points at (Y/n), Mordecai and Rigby. "You three... are the best babysitters we've ever had! You certainly did better than the last few." He holds up his hand, which has three rings with the last few babysitters' souls inside. "I'm impressed. I was sure you'd perish." He said. "Yeah, thanks. Now we had a deal, remember?" (Y/n) holds up the amulet. "Yeah, bring Muscle Man back." Rigby said.
"Alright, fine. A deal's a deal." Death teleports Muscle Man out of the amulet, which also brings Muscle Man back to his original size. Muscle Man cheers and swings his shirt over his head until he realizes it is now too small to put back on. Later (Y/n), Mordecai, Rigby, and Muscle Man are standing outside of Death's house. "You know, it's not easy juggling a full-time job and raising a family, so don't expect it to be so easy to get one of your souls back next time. Which will be soon, what with Muscle Man entering that hot dog eating contest." (Y/n), Mordecai, Rigby, and Muscle Man laugh. "Seriously, you're gonna die in a hot dog eating contest. Ta!" He walks away and closes the door. "Wait, how do we get home?" Rigby asked.
