OK, I am leaning towards the "bulbs do move" camp now.
Another mechanism for movement could be bulb shape
and size changes. Like a worm or snake in slow motion the
shrinking and expanding of bulb parts due to moisture
variation or "intentional" undulations could be very effective
(especially under the weight of the plant).
