I was wondering why everybody has "dancing groot" but they are all stationary.

Why not have him as a solar dancer?

So here is an actual DANCING groot.

Just pop the bottom off a solar dancer from the dollar store (carefully, the copper wires are THIN)

slide it into the hole in pot, glue in place.

remove the magnet from the original dancer and glue in groots bottom cavity.

place in sunlight and enjoy! in action video @ https://youtu.be/0xXAq_mrURA
