The Hambini (ちびちゃんず) are three young, mischievous hamsters. They are owned by a nice woman. Flora and the Ham-Hams take care of them sometimes. They also appear in Hamtaro: Rainbow Rescue.
- When Hamtaro is seen as a baby in Our Biggest Memories!, his eyes resemble those of the Hambini, presumably to make him look younger.
- In Italian, they are called the Mini-Mini. In French, they are called the Tim-Ham.
