SOLD Takara Pocket Critters Dolphin World Keychain Vintage 1993 MISSING TOP

The dolphin moves somewhat when you manually roll the gear. The original top / lid that said, "Dolphin World" is missing. It is hard to roll the gear forward by hand, and I do not know if it will work better with a new top/lid? The video looks more yellowed because my camera does not like to video blues for some reason.
