No, stop, it’s not what you think. This is just about a nice boy feeling proud while wearing a terrific alien costume. The resulting alien has odd purple skin, pointy ears, sharp teeth and weird fins on his head. The most impressive is to see his eyes at the tip of his long antennae. After that, webbed fingers and toes just completes the extraterrestrial effect. The open mouth of the alien leaves space for the boy’s face.
