Minccino and Pachirisu

Minccino (the one with soft white/grey fur):
Appearance: An ultra-fluffy little bun of a baby chinchilla. Its fur is a light pearly gray, almost white, incredibly silky to the touch (the kind that makes you want to bury your face in it), with creamy tufts at the tips of its ears and tail. Its ears are large, round, and pink inside, and it has a little tuft of fur standing up on its head that twitches when it's nervous. Its eyes are enormous, round, brown, and bright, with an expression that says, "Everything's a little dirty... isn't it?". Its tail is long and very fluffy (like a luxurious feather duster), but in its baby form, it looks a bit messy with some tangled hairs. Its paws are tiny and pink on the bottom, and it's always trying to "clean" its face with them.
Personality (in baby mode): He's the calmer and more meticulous of the two when it comes to cleanliness. Even though he's scared of being abandoned, the first thing he does is use his tail to sweep up imaginary crumbs from the bottom of the box (it's instinctive!). When he sees you, he looks at you with pleading eyes and starts rubbing against your hand as if to say, "Please, I'm all messy and cold." He's incredibly sweet and cuddly: once you pick him up, he snuggles up to your chest and starts purring softly while "cleaning" your clothes with his tail (though he's only tickling you). If he sees something dirty (a stain on your shoe, for example), he'll desperately try to reach it and rub it. He's the responsible older brother who takes care of the younger one.

Pachirisu (the one with light gray fur with blue highlights):
Appearance: It's a tiny, round baby version of the electric squirrel. Its body is almost entirely white with a soft, bluish tint, and it has a light blue stripe that starts on its forehead and runs down its back to the tip of its tail (in babies, this stripe is shorter and thinner). Its ears are large in proportion, rounded, and a little droopy, with pinkish insides. Its cheeks are yellowish and chubby (like a Pichu's, but softer), and when it's excited, they spark slightly with static electricity. The tail is enormous compared to its body (almost twice as big), very fluffy, with three small blue bumps on the curved part, but in a baby, it looks more like a giant, messy pom-pom. It has a prominent white tooth that peeks out of its mouth when it smiles, and huge dark gray eyes that give it a "please don't leave me alone" expression.
Personality (in baby mode): He's the more restless and energetic of the two. He's hyperactive despite the fear of being left alone: ​​he wags his tail constantly, making tiny sparks (nothing dangerous, just static electricity), tries to climb the sides of the box and falls flat on his back, and when he sees you, he lets out high-pitched "pachi-pachi!" squeals of pure joy. He's affectionate but clumsy: if you pick him up, he'll hug your hand with his short legs and give you gentle, electric licks. He's easily startled by loud noises, but he quickly gets distracted and goes back to playing. He seems like the typical mischievous little brother who wants attention all the time.

Adult Pokémon can speak like humans, but pups only repeat basic words like "milk" or "hungry" or their names.
