Metapod, Kakuna, Cascoon, and Silcoon

A bundle of white silk lay on a broad yellow-green leaf. A string of silk was wrapped around the leaf's stem to make sure it was securely on the tree. While the bundle was mostly still, a small crack blinked open, revealing a red eye. Good, this evolution was complete. But this was far from the time to relax. She had to complete her new body before she could evolve into it. The new Silcoon turned her attention inward. But not for long.

"Hey newcomer!"

She opened her eyehole back up to look at a bundle of purple silk on a nearby leaf. A Cascoon, a male from the sound of the voice. "Hello."

"Who are you to call her a newcomer?" a third voice added. This came from a brown husk clinging to the nearest branch. From the triangular head shape and body plating, Silcoon knew she was a Kakuna. "You just evolved this morning."

"Well she's newer than me, so I'm no longer the newcomer," Cascoon retorted.

"The more, the merrier," a fourth voice said, accompanied by a wobbling of Cascoon's leaf. Tied under the branch was a green pod. He was a Metapod.

"Hey, watch it!" Cascoon complained. "You could knock my leaf off the tree."

"Oh, sorry." He stopped bounding.

Silcoon watched her neighbors curiously. "Um, Cascoon, did I know you before? Your voice sounds familiar."

"Does it? I guess you sound familiar too." His red eye twitched in looking over her. "Say, are you that cute Wurmple chick who I met while stacking acorns?"

"Yeah, you're the weird Wurmple guy who was trying to make a replica of the Leaning Tower of Pisa out of acorns. That was never going to work."

"Ooo, zinged," Kakuna commented.

"It would've worked if it hadn't kept falling over!" Cascoon insisted. "When I evolve again, I'll find a way to make it work."

"Yeah, you can do it!" Metapod cheered. Then he began singing, "Don't worry... be happy!"

"That's the tenth time you've sung that today," Cascoon said. "It's getting annoying."

"Twelfth, actually," Kakuna corrected. "I've been here all day with him."

Metapod blinked, looking sad. "But I was just trying to help, lighten the mood and all."

"We all have to be working on our next evolution," the brown Bug pointed out. "It doesn't help when you keep distracting us every few minutes."

"It's not like we have to hurry," Metapod replied. "It'll be another five months before spring, when we can come out."

"Do you know how long it will take to make your new body?"

There was a long pause before he answered. "No."

"So get to work already."

"Wait a minute," Cascoon said, his voice a bit panicky. "FIVE MONTHS? I can't move from this spot or I'll ruin the rest of my life! How am I supposed to get anything to drink?"

"You don't have to worry about food if you pigged out as much as I did," Metapod answered.

"I'm not asking about food. I want to know about water! I'm not thirsty now, but I will be."

"It should be okay," Silcoon said. "Dew gathers every morning and, if I heard it right, it'll slide along the silk and be available to drink when you need it."

He looked down, embarrassed. "Oh right, I should have figured. Dew and rain huh? What happens if it gets cold? I heard from a Gloom that it'll all be snow and ice then."

"This process produces enough heat to keep ice from coating us," Kakuna answered.

"How do you know that?"

"I kept warm and toasty during last night's chill. And my Beedrill elders told me not to worry. Nature has everything sorted out for us, so we just have to sit here and work on ourselves."

"It's a lot of work to do, though."

"We've got five months. Don't worry..."

"DON'T START SINGING THAT SONG AGAIN!"

Below his stem, Metapod whimpered.

Silcoon thought about it, feeling bad for the green Pokemon. "You know, if we're going to be neighbors for that long, you ought to be nice to him."

Cascoon made an exaggerated sigh. "Don't remind me. I'd rather think about how to make my tower of acorns work."

"Maybe if you stuck some needles or sticks in them to hold them together," Kakuna suggested.

"How am I supposed to stick needles in acorns?"

"You'll be stronger when you evolve, right?"

"I know!" Metapod called. "You need some Gorilla Glue! That stuff is the strongest adhesive ever made."

"You know the word 'adhesive'?" Cascoon said snidely.

Ignoring him, Metapod went on. "Once you stick something with it to something else, it never comes off. My brother once got stuck to a tetherball with some Gorilla Glue." He closed his eyes. "Poor kid."

"Sorry to hear that he died," Silcoon said softly.

"Oh no, he didn't die. Nurse Joy had to cut him off of the tetherball's skin, but now he has bits of red vinyl permanently stuck to his underside. It wasn't easy for him to walk." He paused. "I wonder if he'll still have the vinyl bits when he's a Butterfree."

"Uh-huh," Cascoon said. "He's certainly your brother."

The branch they were all attached to shuddered. They went silent. After some stillness, the shaking continued. Silcoon and Cascoon had both latched their leaves to the branch; Kakuna and Metapod seemed equally secured. A purple Rattata soon appeared, walking along the branch. Every few steps, he sniffed at it.

"Gotta be something," he muttered. He put a paw on Kakuna, but rapidly snatched it back. "Ouch! What's with the heat?"

"Sorry," she replied. "Don't go stepping on me next time."

He snorted. "Well if you didn't look like part of the branch, I wouldn't have stepped on you." He stepped over Kakuna, then sniffed at Metapod. "Finally." He bit him.

And immediately squealed in pain. "Buzz off!" Metapod shouted. "We Bugs don't need the likes of you around here."

Rattata growled. "You nut! I nearly chipped my tooth on you!"

"Well, you did bite him," Silcoon pointed out.

"If you're gonna try eating us, just know that I have Poison Sting!" Cascoon shouted.

"As do I," Silcoon added.

"Me too," Kakuna said, scratching her claw against another to make a rasping noise.

"Sorry about making a mistake," Rattata replied with a sneer. "I usually don't make my lunch of things that talk back." He then jumped off the branch, making it quiver harder.

"I can Tackle," Metapod said, trying to sound helpful.

"Your shell is probably enough to deter most threats," Silcoon said.

"Then nobody will mess with us!" He took a deep breath and started singing while swinging on the branch. "Everywhere we go, people wanna know..."

"For goodness sakes," Cascoon grumbled.

"Who we are, and we tell them..."

"At least it's a different song," Kakuna replied, barely hiding a giggle.

"We are tigers! Mighty mighty tigers!"

Cascoon's eye slit narrowed. "I swear, when we evolve, I'm gonna make you suffer for every moment of annoyance you've given me! And I'll remember all of them, have no doubt. Now stop shaking my leaf!"

"Oops." Metapod slowed his swing to a stop. "Sorry, I just got excited."

"At least we won't get bored in the next five months," Silcoon said.

"Don't remind me."

A year later, as autumn once again descended on the forest, a Beautifly came upon a Dustox and a Beedrill examining a pile of scattered acorns. "I'm telling you, you need some needles to pin them together."

"You're just obsessed with needles," Dustox retorted.

"Oh hi," Beautifly said. "You guys were my neighbors last winter."

"Hi," Beedrill replied with a salute from her long needle. "It's been a while. How've you been?"

"Great. How about you?"

"I'm fine, but he's still thick-headed."

"Hey!" He shook his head, then said, "Have you seen that crazy Butterfree around? We haven't and I was wondering about him the other day."

"You miss him?"

"No! I was just wondering, that's all."

A sing-song voice broke through the trees. "We are tigers! Mighty mighty tigers!"

"I guess that answers that," Dustox said. "Now if you'll excuse me, I don't want him to know that I'm around."

"Oh my gosh, Dustox! Beedrill! Beautifly!" Butterfree squealed happily as he came into the clearing. "It seems like it's been for-ev-er!"

"I wish it was," Dustox grumbled under his breath.

…

Emerald entry: Its shell is as hard as an iron slab. A Metapod does not move very much because it is preparing its soft innards for evolution inside the shell.

Kakuna Emerald entry: It remains virtually immobile while it clings to a tree. However, on the inside, it busily prepares for evolution. This is evident from how hot its shell becomes.

Sapphire entry: Silcoon was thought to endure hunger and not consume anything before its evolution. However, it is now thought that this Pokemon slakes its thirst by drinking rainwater that collects on its silk.

Sapphire entry: If it is attacked, Cascoon remains motionless however badly it may be hurt. It does so because if it were to move, its body would be weak upon evolution. This Pokemon will also not forget the pain it endured.

I had hit a third of the total amount of Pokemon here. Since these cocoon Pokemon were near identical, I put them all together.
