Dipper and Mabel were glad to be back in Gravity Falls for another summer. Even more so because their uncles had returned from their search of anomalies and had taken ownership of The Mystery Shack again and were happy to let their niece and nephew stay with them.
Dipper was still thoroughly convinced that there was more weirdness in Gravity Falls than what the journals told. So, he mainly spent his days searching the woods and the town for the supernatural.
One morning, Dipper decided to film a patch of red flowers that seemed normal until you tried to pick them; then they would try to eat you. Mabel tagged along as the camerawoman.
"Okay, is it on?" Dipper asked.
"Good to go, bro-bro." Mabel gave a thumbs up from behind the camera.
"Great." Dipper cleared his throat and gestured towards the flowers. "Now, these are flowers."
"Daisies!" Mabel shouted.
"What?"
"They're daisies. You can't just call them "flowers." That's like calling the ocean a giant pool, or calling a reality show a bunch of hogwash, or calling-"
"Okay, I get it. So, these daisies might seem ordinary; but they're actually alive and have been known to eat animals and people if they're about to be touched. I've decided to call them "canniplants."
"Daisies!" Mabel corrected.
"Fine. Cannidaisies. Now, these daisies have been in Gravity Falls-"
"Oooh. What's that?!" Mabel pointed the camera in front of her.
Dipper looked over his shoulder and saw a large, black rat with long, crooked teeth and yellow eyes.
"I wonder if we can keep it as a pet."
Mabel started to walk towards the rat but Dipper grabbed her by the shoulder. "Not so fast, Mabel. Didn't you notice this rat is almost the size of a dog? It's probably another monster."
"Oh, come on. He's probably just had too many cheese doodles. Besides, he looks so sweet."
Mabel walked up to the rat and reached out her hand to pet it. The rat snarled and opened its mouth; thinking fast, Dipper pushed Mabel out of the way and the rat bit into his arm before scurrying back into the woods.
"Oh no." Mabel picked up herself up off the ground and ran over to the injured Dipper. "Dipper, are you okay?"
Dipper grunted and held the bottom of his shirt to his bleeding arm. "It's fine. It just looks worse than it is."
"We need to get you back to the shack. Just follow Nurse Mabel."
Mabel wrapped her arm around Dipper to keep him steady as they headed back to the mystery shack. When they stepped inside, they found Grunkle Ford in the living room, reading through a book.
"Hi kids." Ford greeted. "Back from the monster hunt already?"
"Great-uncle Ford, Dipper was attacked by a large rat!" Mabel said.
"I wasn't attacked. It was just a bite." Dipper corrected.
Ford was immetidately on his feet and examined Dipper's arm. "You said that a large rat did this?"
"Yeah, that's right." Dipper said.
Ford frowned and scooped Dipper into his arms, carrying him to the kitchen. He put him down on the table and began rummaging through the cabinets.
"Where is that first aid kit?" Ford mumbled.
"It's right here." Mabel reached under the sink and pulled out the first aid kit.
Ford took the first aid kit from Mabel, and took out the bandages and the disinfectant. He held Dipper's arm under the sink and began to wash the blood off the bite. He then swabbed the entire arm with two thick layers of disinfectant and wrapped it in the bandages.
"Uh, Grunkle Ford, why didn't you just bandage the bite?" Dipper asked.
"Dipper, you have to tell me. How big was this rat?"
Dipper shrugged. "Probably as big as a small dog. Mabel was about to pet it, so I tried to stop her, that's when it bit me."
"It was that big, huh?" Ford said to himself.
"I'm sure it's nothing to worry about." Dipper said.
"Do you feel feverish?" Ford felt Dipper's forehead. "Thank goodness. Perhaps it was only a large rat, still if it wasn't..."
"Grunkle Ford, what's going on?" Dipper asked.
"N-Nothing. Tell you what, how about you go on to bed?"
"But what about dinner?" Dipper asked.
"You need your rest. We'll bring a plate to you in the attic. Now, go on."
Ford ushered the twins upstairs. Once they were out of sight, he ran back to the kitchen and grabbed the phone.
"Operator, get me the best doctor in Gravity Falls. Tell them I need them I need them at The Mystery Shack right away." Ford hung up the phone and couldn't help but notice the little droplets of blood that had been left by Dipper's bite. "I hope I'm wrong about this."
