Skeleturtle

Skeleturtle is an mysterious bone that appears in Mothra vs. Godzilla of 1964. Its actual status is of an irradiated creature.

Skeleturtle is purely white and gray, with black eyes, and a featureless white shell. It has a long neck, and very short limbs, which have small bone fragments visible.

Skeleturtle's direct origins are unknown, but it is possible that it is a radiation-modified turtle on Infant Island or a turtle of a species unknown.
