Memetchi is a female Tamagotchi character originating from the Tamagotchi Connection/Plus virtual pets, later appearing in media like the "Let's Go! Tamagotchi" anime and films. She belongs to the Meme Family with her younger sister, Imotchi. Sharing a close childhood bond with Mametchi and Kuchipatchi, she maintains this friendship into adulthood.

Her design features large sparkly eyes and a prominent right-swirling curl atop her head, serving as both visual trademark and functional navigation aid. This curl holds deep personal significance, with damage or criticism provoking strong reactions. Memetchi typically has an orange body with thin limbs, though colors vary across media.

She maintains a feminine, cheerful, and childlike demeanor with strong interests in fashion, accessories, dancing, and dress-up. Sensitive about her appearance, especially her signature curl, she becomes defensive when insulted. A recurring rivalry exists with Makiko, primarily focused on curl aesthetics, though Memetchi prioritizes friendship over vanity. Despite occasional stubbornness and temper, she demonstrates loyalty and care for friends.

Her narrative includes relocating to Dream Town alongside Mametchi and Kuchipatchi to study hairdressing. There, she resides at Salon De Dream and joins the Kira Kira Girls as a saxophonist, reflecting her interest in style and beauty. Later storylines, like the Tamagottsun event, facilitate reunions with her original friend group.

Interactions highlight her role as an energetic "mood maker" who uplifts others. Hobbies include collecting spiral-patterned items, owning swirly-faced teddy bears, and enjoying pink roll cakes. Favorite colors are orange and pink, with preferred foods including cupcakes and oranges; she dislikes fish.

Memetchi's character remains consistent across adaptations, emphasizing her vanity-combined-with-kindness duality, dedication to friendships, and growth toward professional aspirations in beauty and fashion industries.
