Hey, Bill. Have you ever come in contact with the Krookodile line?

Yes indeed! I take it this is meant to be a request? If so:

Sandile
The Desert Croc Pokémon
Type: Ground/Dark
Official Registration #: 551
Entry: Sandile are a crocodile-like pokémon with two notable adaptations for life in the desert: skin the color of sand and the unique habit of traveling across the dunes with most of their bodies buried. Because of both adaptations, sandile are extremely difficult to spot as they move across the Unova desert, but despite this, they are also timid, easily panicked pokémon that have a tendency to snap at whatever unwittingly walks too close for comfort with their sharp jaws, regardless of whether or not that threat can actually see them. Thus, the writer has only one piece of advice for anyone who intends on traveling through the Unova desert: wear boots.

Krokorok
The Desert Croc Pokémon
Type: Ground/Dark
Official Registration #: 552
Entry: The evolved form of sandile, by battle experience. Krokorok are very similar to their evolutionary predecessor, save for three key differences: size, the tendency to travel in packs of three or more, and the fact that they will snap at hapless travelers not out of self-defense but instead because they enjoy toying with anyone who has the audacity of traveling through their territory. Thus, should you wish to travel through the deeper parts of the Unova desert where krokorok tend to nest, the writer has additional words of advice for you: wear heavier boots and bring a water-type.

Krookodile
The Intimidation Pokémon
Type: Ground/Dark
Official Registration #: 553
Entry: The evolved form of krokorok, by battle experience. Despite the fact that its predecessors call the Unova desert home, Krookodile are not native to that region but instead Australia, where the harsh environs have forced the local krokorok to evolve into larger, more aggressive forms with jaws capable of smashing through cars. This does not seem to faze the Australians, who seem to have made it a sport to find and wrestle wild krookodile to the ground. In light of this, the writer has only one last word of advice for his readers: don’t go to Australia.

Please do Sneasel and Weavile, Bill.

Certainly!

Sneasel
The Sharp Claw Pokémon
Type: Dark/Ice
Official Registration #: 215
Entry: In Johtonian folklore, there is a creature called the kamaitachi, which was originally depicted as an invisible beast or whirlwind that lacerated hapless wanderers, leaving deep but painless wounds. Later research uncovered the fact that these demons were actually teams of sneasel that used Icy Wind to startle victims shortly before sneaking up on them to take them down. It goes without saying that this is yet another reason why Johtonians inherently possess an innate urge to set fire to everything within reach.

Weavile
The Sharp Claw Pokémon
Type: Dark/Ice
Official Registration #: 461
Entry: The evolved form of sneasel, by battle experience if holding a razor claw at night. Upon evolution, weavile become far more intelligent. Not only they have the ability to communicate through written language (which they carve on boulders in their territory to communicate with other weavile), but they also have the ability to coordinate and strategize, which they do in small but lethal groups. This would be unfortunate for Johtonians, except we had the foresight to gather all of our razor claws and export them to Sinnoh under the guise of a diplomatic gift. This, as expected, did not improve Johtonian-Sinnohian relations, and because we have subsequently recognized this as a jerk move, Johtonians as a whole didn’t put up much of a fight when Sinnoh built the Battle Frontier and exported to our region something worse than weavile: tourists.

Pancham and Pangoro

{This and the following four entries are by request of @the-firebrand. Thanks! 😀 —The Mod}

Pancham
The Playful Pokémon
Type: Fighting
Official Registration #: 674
Entry: This two-foot-tall panda pokémon will do anything it can to make its enemies take it seriously. Thus, it frequently adopts a confident swagger on the battlefield while chewing on a leaf to make it look tougher than it actually is. In truth, this is a cuddly pokémon that can be easily distracted with petting, although this is rarely recommended, not because it can pack a powerful punch (although it certainly can) but instead because this embarrasses it immensely.

Pangoro
The Daunting Pokémon
Type: Dark/Fighting
Official Registration #: 675
Entry: The evolved form of pancham, by battle experience if raised alongside a dark-type pokémon. Unlike its previous form, pangoro are notorious for being seven-foot-tall, 300-pound mountains of muscle, claws, and rage. If confronted with anything that even slightly resembles bullying, it will charge the offender and smash them with their giant paws, which are strong enough to snap telephone poles in half. Incidentally, this reaction also applies to anyone who subjected them to humiliation as pancham, so to those of you who had a habit of cuddling your pancham because they were fuzzy and adorable … never evolve your pancham. Ever.

Corphish and Crawdaunt

Corphish
The Ruffian Pokémon
Type: Water
Official Registration #: 341
Entry: Its hardy physiology enable it to thrive in a variety of environments, including heavily polluted lakes and streams. For this reason, Hoennian opinion about corphish tends to be divided. On the one hand, its abundance means that corphish are plentiful and easy to find and capture, as it can survive practically any form of water besides a pot of boiling broth. On the other, just because you’ve boiled the thing does not mean the corphish you’d caught from the river next to the power plant is edible.

Crawdaunt
The Rogue Pokémon
Type: Water/Dark
Official Registration #: 342
Entry: The evolved form of corphish, by battle experience. Said to be the modern-day relative of armaldo, crawdaunt similarly possess hefty bodies and large, heavy claws capable of doing massive amounts of damage to its enemies. However, unlike armaldo, crawdaunt do not have rocky hides that make physical attacks difficult. Rather, they have extremely foul tempers and may attack at the slightest provocation—such as, for example, the scent of tamato berries, one of the primary ingredients for the cocktail sauce normally served with cold shrimp.
