Diglett but it's an ostrich that puts its head in the ground, but hey! Plot Twist! Actually the neck and the body are of 2 different Pokémon that collaborate with each other (like Skeledirge and his bird), so we don't know the body of the neck and we don't know the head of the body, so as to always keep the mystery of their true appearance alive 😂
