The moss froglet (Crinia nimbus) is a species of frog in the family Myobatrachidae.

[2] The male advertisement call is a series of tok's,[2] likened to a ping-pong ball being dropped on wood.

[5] They live in moist, cool, alpine habitats, poorly drained sites in moor land (shrubland and heath), and rainforest, from the sea level to 1,287 m (4,222 ft).

[1] They are mostly quite cryptic and hide in vegetation and in the nest cavities, but males can be heard calling in spring to summer.

There are no know threats to it, although the terrestrial nests are vulnerable to trampling by animals and people (tourists and researchers alike).
