Here's what I thought up of. Hope this helps!
Classification: Parent Pokemon
Dex Entry: Kyouan Kengaskhan are more lax parents than their common counterparts, allowing the young ones more free range. Notably agile, they can hop long distances in a single bound!
Classification: Cute Pokemon
Dex Entry: People are drawn to them for their adaptability in new places and cuteness. Dote on them too much, and they'll become spoiled and fussy!
Classification: Seabed Pokemon
Dex Entry: Discovered only in recent years, this pokemon is often found feeding on plants in excess. Their feather-like ears can pick up sudden changes in currents.
Classification: Litter Ball Pokemon
Dex Entry: Drawn to messy environments, collecting dust bunnies and litter as they hop along. It will become a Trubbish if it gathers a week's worth of trash.
Classification: Snow Monkey Pokemon
Dex Entry: It makes a roaring howl that that sends vibrations through the snow and ice to alert the rest of its pack. They are more lively in blizzards.
Classification: Fast Chick Pokemon
Dex Entry: Once they can leave the nest, they'll dart around the woods for Berries. The beak is like a small dagger, so be careful!
Here are some new entries for you:
Classification: Crash Cow Pokemon
Dex Entry: The tuft of fur on their heads is tough and durable due to continuous ramming. If you tug on it, it'll use you for practice!
Classification: Little Rabbit Pokemon
Dex Entry: Proper care will allow the white fur to thicken and improve in quality. Their timidness is considered endearing, but will knock the wind out of you with a headbutt if stressed.
