Rumble Robots Mefisto & Clamster: Unfortunately both Mefisto and Clamster no longer punch/move their arms anymore. Clamster's motor goes off but the arms do not move and Mefisto just makes an electronic sound instead of punching. I have tried swiping all of the cards and using fresh batteries but the internal gears are likely messed up. They still drive, shoot their laser and make sounds though! This listing is more for people that want them as a display piece or have the technical knowhow to fix internal gears/motors. There is some battery corrosion on both controller's battery compartments and a little corrosion on the inside of the Rumble Robots battery compartments.  One of the Laser 2 cards is fairly bent up. The rest are are in alright condition but have some wear from being scanned. These items come from a smoke-free environment and I am the original owner of them. USA buyers only! Make sure to check out my other items and products I have for sale. Thank you!
