Mabel, while out on a happy midday stroll through the woods, felt as though she had no worries with the sun shining down and fertile smell of a woodland all around her.
"Yep, it's a great day today," she said aloud. "Nothing is bad right now. Too bad that Candy and Grenda are both sick today."
Just when she started to feel a little bit lonely, she spotted Gompers the Goat feeding, straight ahead of her. He was eating some fresh Ferns, loving every tasty bit of their leaves.
"Hi Gompers!" spoke Mabel with a smile, walking over towards the cud-chewer, "Why are you so far in this part of the forest? Are you just looking for fresh new greenery to eat? I don't blame you whenever I'm looking for new food to eat too."
Gompers just looked at her for about a second and went back to eating. Right before Mabel could pet Gompers on the back, the noise of large, thumping hooves came from the nearby undergrowth. Gompers bleated in surprise and ran to hide right behind Mabel.
"Who's there?" Mabel asked the noise, "Show yourself, please?"
"I am not of your kind, young lady," spoke the thing in a stern and deep male voice. Out of the undergrowth emerged a tall, bipedal humanoid-type creature with big cloven hooves on its hind limbs. It also had Ape-like hands, a Deer-like tail and (most oddly of all) the head of an Elk with great antlers. He even carried a bow and arrow set with him.
"Wow!" said Mabel in awe, admiring the magnificent appearance of this being (Gompers had already run back to the Mystery Shack for cover), "Hi, I'm Mabel Pines. Who are you?"
"I am Hylaeocervopus," spoke the creature with a formal bow, "I am an Elkron. My duty is to protect these forests from anything harmful, not to mention I also have to be sure...they...are sealed away."
"So what do you protect the woods from?" asked Mabel curiously.
"Mostly from the ravaging pollution and overhunting by Humans, your people," answered Hylaeocervopus.
"But I don't harm the land and its living things," said Mabel, sweetly, "I'm not like most Humans."
Just at that moment, in came Old Man McGucket, running and laughing mindlessly as usual, right by Mabel and the Elkron. "YEEEEEEHAAAAAAHHHH! I've seen strange things in my day, but none as strange as Deer-Head right there!" The crazy old man gestured to Hylaeocervopus as he ran by, dropping an empty beer bottle as he ran out of sight.
"I think I see why you have a poor opinion on us," said Mabel, feeling a bit embarrassed by McGucket's odd behavior around this supernatural protector of the forestlands.
Hylaeocervopus nodded in agreement and was just about to leave when Mabel then asked, "Hey, by the way, what did you mean by you have to be sure that 'they' are sealed away?"
"That information is privileged, young Mabel," responded Hylaeocervopus, worried about a secret being revealed, "Let us just say that I am protecting this land from an unforeseen disaster. A disaster from...a swarming horde..."
And with this mysterious answer, the Elkron vanished back into the forest. Mabel decided that she should find out more about this "swarming horde" back at the Mystery Shack. "Time for me and Dipper to find out what Mr. Hylaeo-whatever is hiding," she said as she skipped back to the Shack.
