The Mystery Bones of Infant Island (インファント島の怪骨?), also known as Infant Island's Kai Kotsu is a turtle Infanto-jima no kai kotsukaiju created by Toho that first appeared in the 1964 Godzilla film, Mothra vs. Godzilla.
The official name "Mystery Bones of Infant Island," is a translation of the name for the creature found in a 2012 toy of it, which reads "Infanto-jima no kai kotsu." Officially licensed t-shirts featuring Skeleturtle that were sold in Japan refer to the creature in English as "Infant Island's Kai Kotsu."
The Mystery Bones of Infant Island is purely white and gray, with black eyes, and a bland, pale shell with no visible scutes. It has a fairly long neck, and very short limbs, which have tiny bone fragments visible.
The Mystery Bones' direct origins are unknown, but it's possible that it was either a turtle mutated by radiation on Infant Island or a turtle of an unknown species.
The Mystery Bones made a very short appearance on Mothra vs. Godzilla, lasting only about 38 seconds on screen and in the background. It was found on Infant Island, which had a lot of radiation and lifeless skeletons lying around. None of the characters ever directly interact with or notice it.
- The Mystery Bones is one of four minor Showa era monsters, who include the Giant Lizard, the Giant Octopus, the Giant Condor, the Giant Sea Serpent, and Skeleturtle, to have received an official toy. The others are the Giant Octopus, the Giant Condor and the Giant Sea Serpent, with the Giant Lizard having no toy.
