Derpshorts

The three young Pokemon stood outside of the rather ominous entrance to the tomb.

"You go in first."

"N-no, you do it."

"Oh, Arceus. I'll do it, since you two wimps don't have the guts."
The Pancham shoved the Elgyem and and Charmander to the side and took a few steps in, balking at the sight of the dark tunnel. He turned back to the others, looking a little nervous. "Well? What are you waiting for? Come on, unless you really are gutless?"

"W-well," the Elgyem stuttered, "the grown-ups always tell us not to come here, and-"

Pancham groaned. "Fine. Charmander, you're coming, right?"

The Charmander muttered at his feet. "Yeah, I guess..."

"Alright then, let's go." Pancham turned and walked into the tomb, followed by a reluctant Charmander. Elgyem sighed and went after them. They were his friends, after all. Even if that entailed going into the incredibly scary tunnel.

Charmander providing light, the three walked a short ways in, and Elgyem noticed some writing on the wall that looked like some sort of warning. He was about to say something, when he noticed that Charmander and Pancham had already moved past him into some kind of room. He ran up, not wanting to be left alone, and writing forgotten,

"Woah, check all this stuff out!" Pancham was rooting around in a old chest and pulled out a valuable-looking necklace. "The grown-ups were crazy for not letting anyone in here. This must be worth a fortune!" The three went around the room, exploring around.

"Hey, guys?" Charmander waved at the two. "Look at this thing." He held his tail in front of him, illuminating a large, golden sarcophagus. Pancham ran up to it.

"Betcha there's even more cool stuff in here. C'mon, help me open it!" He started to tug at it.

"Uh, Pancham?" Elgyem said, suddenly remembering that maybe-warning. "That might not be a good idea"

"What?" Pancham turned around torward him. "Not like it's gonna come to life or anything like that." Just as he said that, the sarcophagus moved. A black aura surrounded it and four shadowy hands sprouted from it. Pancham looked at the two stunned Pokemon in front of him. "What are you two looking at?" Charmander just pointed, as the now floating coffin's faceplate slid back to reveal a red eyed, shark toothed black face with a thunk. Pancham turned slowly to face it, and the Cofagrigus cackled madly.

"Gold! Gold! Thieves! Thieves of my GLORIOUS GOLD!"

"I-I'm sorry sir, we just-" Pancham backed up hastily as the Cofagrigus fell down onto it's hands and scuttled torward the three.

"Thieves! Thieves of my treasure! My GOLD!" It lunged for the three, and skidded across the ground as the children scrambled out of the way. It sprung back up with amazing speed and managed to grab Charmander's tail. Before anyone could react, Cofagrigus opened itself and threw the poor lizard in, snapping shut and plunging the room into darkness.

"Ch-Charmander! You...you..." Pancham saw red, and charged for Cofagrigus, barreling into it. But Pancham passed right through them, and ended up sprawled up on the floor. "Wha- How?" The Cofagrigus only cackled again and swiped him into a wall. As it advanced on the groaning Pancham, the Cofagrigus suddenly looked confused for a moment, then was surrounded by a pink glow. Behind him, Elgyem was hovering off the ground, eyes glowing purple.

"Leave him alone!"

The Cofagrigus just stood there as Elgyem tried to do something to the Pokemon, as it laughed insanely the whole time. Elgyem suddenly quivered and crumpled to the ground, his power spent, and the coffin Pokemon got up, none the worse for wear.

"Thieves! Thieves pay! Pay for stealing my glorious gold!" It laughed again, as a large shadow loomed up behind it.

"Well hey there, friend." Pangoro said, as it picked up Cofagrigus, flipped it, and slammed it into the ground headfirst.

"Gold, gold, gol..." The coffin finally fell silent, and Pangoro wrenched it open to find a unconscious Charmander. He picked up the other two, walked outside, and dropped them unceremoniously on the ground. They groggily got up, bruised and battered.

"What. The Hell. Were you three thinking."

The trio immediately blanched as they saw who exactly their savior was.

"H-hi, dad." Pancham waved meekly.

"If your friend here-" Pangoro gestured at Elgyem, "-hadn't telepathically told me you were in trouble, Arceus knows what that maniac would've done." Pancham shot a glance at Elgyem and began to say something. "Don't even start. It's your own fault you got you and your friends in that mess. You've been told not to go in there. You two, you can go."
Charmander and Elgyem ran for it before he could change his mind, leaving the unfortunate Pancham to a very severe scolding.
