Listics

Matt and Wendy were exploring.  In the barn they climbed the steep steps to the hayloft.  The hayloft door stood open, a gaping maw ten feet above the ground, about six feet square, convenient for loading bales.  Molly raced up the stairs past them.  When she got to the loft she must have looked through that opening and seen her frisbee on the ground outside.  Matt got to the top in time to see her launch herself out the door, land (none the worse for wear), and come charging back up the stairs with the disk in her mouth.

Aussies have a levitation gland, I think.
