The seasons.
Homicide
Night, day.
creation.
wildlife.
destruction.
war.
famine.
Saruman.
awful drivers.
nature.
feaces.
burials.
hobbits
cats getting stuck.
leopards kill.
Firemen.

If any sound is actually made when one of their relatives falls down in the forest and nobody else is around.

Baloo's satisfaction.
Bagheera's exasperation.
The king of the swingers, singing.
