What do you call a tiny kangaroo?

The smallest kangaroo is the musky rat-kangaroo, with an average length of 23 centimetres. The musky rat kangaroo lives in the dampest parts of the tropical rainforests in north Queensland. See the related link below.

It is not the smallest marsupial, however. The smallest marsupial is the long-tailed planigale, with an average body length of 55-65mm.
