The Tjerwerk Fireball Humanoid is a creature sighted in Tjerwerk, Friesland, the Netherlands, in 1927. It was sighted by a man named Lieuwe Klaasens and a local pastor. They saw what resembled a fireball descending from the sky, and then morphing into a humanoid shape. This figure walked toward a Frisian burial ground, called a terp, before rolling back into a fireball and disappearing into the sky. Citations: Rosales, Albert.
