Pixel Chix
A little plastic house with an LCD screen and a digital girl living inside it—part Tamagotchi, part dollhouse. You fed her, played games, dressed her, and sent her to bed, and if you neglected her long enough she'd pack up and leave.
Mattel released Pixel Chix in 2005: a handheld life-sim shaped like a small plastic house, with an LCD screen in the front showing a pixel girl going about her day inside. You took care of her—feeding her, playing games, changing her clothes, sending her out and putting her to bed—and progressing unlocked new items and activities. It came with a nurturing catch straight out of the virtual-pet playbook: ignore her and her skills dropped, and neglect her long enough and she'd "leave," only returning after a reset.
The feature that set Pixel Chix apart from a Tamagotchi was physical connection. Houses plugged into one another through USB-style connectors on the bottom, letting your character visit or move between houses, so kids could link up cottages, mansions, and lofts into a little digital neighborhood. Mattel expanded the line with color and style variants (including a purple loft sold only in Europe) and playsets like the Love 2 Shop mall and Road Trippin' Cars. It was a genuine mid-2000s craze before Mattel discontinued it in 2009—a dollhouse you could hold in one hand, with a resident who had opinions about being left alone.
