Whoops! Almost forgot that this was a thing! - SGA
"...Ohhhh... oh, whoa." The boy gasped let out a loud in amazement. His pen now sounded like a tiny machine-gun as he clicked it excitedly. "So the town park is lying on top of an ancient...interesting, but if they knew, why would..."
There were really very few people who could get as intensely immersed in a book as Dipper Pines could. That held especially true especially true for whenever he cracked open the mysterious journal. Nearly his entire face now lay buried in the yellowed pages of strange notes and detailed hand-drawn illustrations that now soaked up every ounce of his hyper-concentrated attention.
"Temple ruins….maybe...buried under….baseball diamond…." He muttered as he jotted down his thoughts into a battered notebook.
The boy was so focused on his reading that he failed to notice the curious lump that suddenly started to literally worm its way into the attic room. It looked like a normal sleeping bag, except that unlike other sleeping bags, this one not only moved on its own but also giggled like an over excited twelve-year-old girl. Slowly it wriggled across the floor, taking full and skillful advantage of the fact that the unsuspecting boy was hopelessly distracted.
It wasn't until it had loomed up directly next to the bed and case a lump shadow did Dipper notice that something was seriously amiss. "Wha-"
"HUMAN WORM!" His attacker joyously announced, then promptly erupted into chirping laughter as it started to furiously flop on top of its badly startled target.
"Hey, what are-augh! Quit it!" Dipper flailed about in a panicked, and ultimately futile defense against the silly assault. With a hoarse, cracking cry he accidentally rolled right off the bed and into a heap.
"Mmmm! Yummy!" The self-proclaimed "worm" eagerly swooped in. The front of the sleeping bag opened wide, and suddenly everything became dark as Dipper found himself half-swallowed by its mouth.
"No! Cut it out! Stop! Stoppit!" He thrashed and whined in protest, all to no avail. Inside the bag, he could feel a pair of hands grab him by the arms and start to drag him in even deeper, despite his best efforts to squirm loose. "Mabel, no!"
"Om nom nom nom nom!" It replied in a bubbly rumble that was very clearly a Cookie Monster impression."Me love eat nerdy brothers! Om nom nom!"
Dipper's waist, kicking legs, and finally even his feet pulled out of sight, temporarily leaving nothing left but one very overcrowded bag. However, barely three seconds passed before he was suddenly shoved back out, with an appropriate sound effect accompanying his rough exit.
"Ptooey! Yuck, tastes too much like a butt!" Upon reaching the punch line, Mabel absolutely lost it. She immediately started laughing so hard that she could barely unzip and crawl out of her improvised costume. As she hugged her legs, rolled from side to side and giggled like a little tween maniac, her shaken twin needed to take a few moments to get his bearings together before he could sit up and respond appropriately.
"Can you please tell me why that just had to happen?" Dipper hurled his arms in the air as he let rip with a frustrated yell.
It took a few moments until she could calm down enough to answer. Still trembling with unbridled glee, his twin sat up, affectionately booped her brother in the nose and replied innocently, "Because it was getting way too quiet in here!"
Immediately she erupted again into a one-person symphony of mirth. While her squeaky laughter continued to fill the room, her exasperated brother flopped backwards onto the floor.
"That actually makes so much sense, it's honestly kind of upsetting me right now..."
