2014 Lego Hero Factory Jumper Figures - Set of 6

A collection of six small, insect-like LEGO Hero Factory Jumper figures from the 2014 Invasion from Below wave, featuring a black upper shell connected via a Technic pin to a brightly colored soft plastic undercarriage and legs.  In good condition. You push down on the pointed black piece to make them jump. As it pointed out of mine and a video of showing how they work, how do you push them to make them jump, it states they do not have any heads. But this looks like it would be the back end of each that you push on to make them jump.  From a non-smoking home
