Options for making a moving/wiggling stem for a flower toy? Answered

I am NOT talking about those flower desk toys that make the entire flower wave. What I would like is to make a toy flower that had a stem that could wiggle if you pushed a button or triggered a sensor. It would move like the picture below. I have no idea what the mechanism would be inside the stem so I would like some ideas on that. The simplest/cheapest mechanism would be the best option. Thank you!

This common wooden snake toy is made of several half-rounds glued to either side of a strip of fabric. To animate it, drill matching holes through the blocks before gluing. Attach one end of the 'snake' to a baseplate. Then, fix elastic threads to the top of the 'snake', then run the threads through the holes, one on either side, occasionally crossing them to get the s-curves. The threads should then be attached to either end of a lever with a pivot in the middle (so that when one end goes up, the other goes down). Put a tension spring on one side of the lever, and link your button to the other. You can cover the stem with anything that has enough stretch to allow the wiggle, like a sewn lycra tube. Have fun!

With today's efficient motors and solar cells. The whole contraption would work off the room lighting and respectfully stand still when a co-worker approached your desk. Diminishing the available light. No buttons, batteries or remote sensors needed.

A bent stiff wire inside a flexible hose or tube of some kind, connected to a slow turning motor like the one in a microwave oven that makes the plate turn.

As the motor turns the wire turns inside the tube making the stem of the flower wiggle.

Stem made from beads, string through, small pull-relais to tension the string - wiggles.....
