The Hambini (ちびちゃんず, Chibi-chanzu/Chibi-chans) are three young, mischievous hamsters. They are owned by a nice woman (whose name is currently unknown). Flora and the Ham-Hams take care of them sometimes.
They also appear in Hamtaro: Rainbow Rescue.
In Italian, they are called the Mini-Mini. In French, they are called the Tim-Ham.
