Embryonic development looks like a chronometer. Next to the future spine, cells are differentiated with a certain spacing that scientists call "somites." These are structures that grow, change shape. Somites will give rise to vertebrae, ribs, and axial musculature.
Somites are transient epithelial structures. These structures form early in embryonic development and originate with other important structures in the vertebrate organism.
I would create a monster that has really long legs and is really big and so it would make people stay away from it, because they know it is going to hurt them if they go by him.
