Since 1954, Godzilla—née "Gojira"— has stomped over miniature Japanese cities. The character is a movie icon. But have you ever wondered what's inside the enormous kaiju ? (Well, besides Godzilla guts...)
This, apparently. The illustration seems to be from a Japanese children's book, and it lists the different parts of Godzilla's anatomy, including his brain, uranium gland, energy intestines, and more, such as the organ in which nuclear fission occurs. The drawing even points out Godzilla's knee joint, which I reckon is pretty interesting to little kids, but less so to the inhabitants of the cities Godzilla destroys.
