This was originally i'm a faller's story Ash and Pines, But he gave it to me! :D Hope you enjoy!
Ash POV
"Biiiiiiiiii!"
The cry rang through the forest.
"Pika-pi!" the Pokemon hitching a ride on my shoulder exclaimed.
"Sounds like Celebi, huh Pikachu?" I laughed.
"Pika!" Pikachu agreed.
A blast of green light zoomed past my head. Pikachu tumbled from my shoulder, landing on the ground in a sitting position. Celebi.
"What's taking Brock and Misty so long?" I grumbled to myself. They had simultaneously decided that they needed to relieve themselves, so we decided to meet here. I was fine with it, but they seemed to think otherwise, seeing as they hadn't arrived yet.
"Bi!" the floating green Pokemon announced, stopping a few feet away from me.
"Pikachu!"
"Hey Celebi!" I greeted.
"Cele!"
"Remember me from earlier?"
Celebi nodded, its entire body swinging up and down.
I laughed some more. It's mouth opened in a smile, as if it too were laughing.
I felt Pikachu's leg rub against my cheek. I guess he managed to climb back on me.
Suddenly, the forest stilled. Celebi's eyes were shut, creating an ominous feeling about the place.
A small mumble of confusion escaped my lips as a powerful wind surged through the area, disturbing the quiet.
Celebi began to fly around me at an increasing speed while a sound that reminded me of a playful giggle seemed to emanate from it.
"I think it wants to play!" I realized.
As soon as those words were said, an eerie green glow enveloped the surrounding trees. I gasped.
"Are we traveling through time?" I asked Celebi. It didn't respond.
Then everything stopped.
We were in a forest again, but it felt different.
Birds chirped in the trees, but they didn't sound like Pidgey, or any other Pokemon for that matter.
And Celebi was nowhere to he seen.
Dipper POV
An unearthly shriek sounded from somewhere in the woods.
"What was that?" Mabel asked.
"I have no idea," I muttered.
"I know you don't. It was a rhetorical question," she explained. I rolled my eyes amusedly.
"Hey kids! Did you hear that too?" Grunkle Stan questioned, just now exiting the Mystery Shack to join us on the lawn.
"Sure did," Wendy told him. She rolled up in the Mystery Cart with a rumble, and pulled in near the front door. "The whole town's goin' nuts!" I loved how calm she was. "And did you see the trees? They were like, glowing or something!" Her eyes lit up when she said the last part, as if glowing trees were the most amazing thing in the world. That would be pretty cool, though.
"Ha! Glowing trees..." Stan grumbled to himself.
If there really had been glowing trees, then that would be awesome!
But still, that scream... And the trees...
I had to investigate this.
