Nothing says Christmas in Japan more than an animated Santa powered by an electric eel.
For five years now, the aquarium south of Tokyo has featured an electric eel which lights up a Christmas tree.
It's a way to get out the essential message of Christmas --don't stick your hand in the eel tank! Or, perhaps, it's an alternative energy holiday.
This year however, the display has been upgraded, as the eel is collaborating with an electric floor pad.
The pad, when stepped on by visitors, generates electricity to illuminate additional lights on the tree.
The South American eel can produce up to 800 volts of electricity, at one amp.
Each time the eel moves, it generates enough electricity to light up the Christmas tree.
Apparently, the eel also powers the animated Santa who appears to be doing the hokey-pokey.
