Mighty Beanz is a line of toys that started in Australia in the early '00s and was relaunched in 2010. This guy is #7 of the first relaunch group in 2010 and simply named Skateboard Bean. Inside this plastic bean is a free-moving metal ball that can make the bean jump slightly when handled. In addition to putting beans in collector cases there are also tracks that they can race on. They go down the tracks end over end a little like a slinky. That's pretty much it. I think it is primarily a toy just to collect. At least there is a gross-out factor that harkens back to the glory days of my childhood.
