Admittedly the image quality is “this meme first appeared in a dirty magazine in 1986 and has been re-compressed twice a year since the internet was invented”, but there are falling lines above the cucumber, and a little puff of smoke where it hits the ground. It’s depicted as falling out of a tree.
It’s common to use a trellis with cucumbers to have their vines grow vertically instead of covering all of the horizontal space of a garden. That makes cucumbers “hang” in the air like a fruit on a tree, and would lead to those motion lines in a fall.
