Part of a completely eco friendly line of toys from Ecotronic, the Mr. Robot Head toy, $32.99, is based on the “Operation” style challenge of moving a metal ring along the twisty, turny metal wire without letting the two metals touch. If the user touches the wire with the metal loop, Mr. Robot Head will buzz and flash, letting you know you are going to have to try again. The coolest part? This toy is completely eco friendly and does not require any batteries. To charge the toy, turn the hand crank in the back of his head and keep the fun going indefinitely.
