Walkie Bits Momo-kame, Cheri-kame (not sold separately) When you pull the candy from their mouths and the string returns, they vibrate and move forward! I purchased these over a decade ago, so Momo-kame has a stain on its head (see the last image). I stored them in a dark place after purchase. They are no longer sold, so they are difficult to obtain. Total length: Approximately 8.5cm Operation confirmed. Please comment if you have any other questions. Immediate purchase is OK. #CandyToys #HeiseiRetro
