The wind blows slightly through the trees, russeling the leaves.

A gust of wind sweeps a few leaves across your footpaws.

A leaf floats idly through the wind.

@succ start_bg={lexec:{&cmd}.cmd}

drop tree

Type start_bg to start showing messages, stop_bg to stop, faster_bg to show them often, and slower_bg to slow them down.

Be sure to @set start_bg=myobject:#id of the object created for this to work!

E.g., do a look, and if the stone is #3432, then enter:

@set start_bg=myobject:#3432

The name 'myobject' is exactly as it should be (don't put 'tree')
