Minccino, Pichu, buneary, rescued

Appearance:
It's a tiny electric mouse with a round body and bright yellow fur. Its ears are large, pointed, and have black tips (like a tiny lightning bolt). It has very noticeable pink cheeks that puff out when it's happy or accumulating electricity. Its tail is like a small black lightning bolt. In the picture, it has a mischievous and cheerful expression, its mouth open as if it's telling a tale of mischief.
Personality:
He's the most energetic and mischievous of the trio. After his rescue, Pichu developed a playful but somewhat clumsy personality: he still doesn't have full control over his electric shocks, so he sometimes gives little static "kisses" when he gets too excited. He's very affectionate, loves to hug, and climb on shoulders. He's afraid of doctors and wires, but with patience, he's becoming a brave little guy who protects his stuffed animal siblings.

Buneary (the middle brown one)
Appearance:
A very round and cuddly chocolate-brown bunny. Its ears are long and end in large, cream-colored pom-poms that look like clouds. It has a small pom-pom tail and short legs. In the picture, it's wearing a blue bow to match its companions and has a sweet and curious expression.
Personality:
He's the most sensitive and emotional of the three. The lab made him somewhat withdrawn at first, but now he's blossoming. He's affectionate and loves giving big hugs with his pom-pom ears. He can be shy with strangers, but with his two brothers, he's playful and a bit bossy (he likes to decide which toy they'll play with). When he gets scared, he hides his face in his pom-poms.

Minccino (the gray one on the left)
Appearance:
A chinchilla-type Pokémon with incredibly soft, shiny, silvery-gray fur. Its ears are enormous and rounded, with pink insides, and it has a long, fluffy tail that resembles a feather. It wears a blue bow that adds an elegant touch. Its large, expressive eyes convey sweetness and intelligence.
Personality:
He's the "responsible brother" of the group. Minccino is obsessively clean (a natural trait of his species), and since being rescued, he's dedicated himself to tidying up the toys and cleaning up any stray fur. He's a bit shy at first, but once he trusts you, he becomes extremely affectionate and protective. He likes to snuggle up in soft blankets and hates mess (sometimes he even tries to "clean" Pichu's face with his paws).
