Moonsnake

Moonsnakes are species that appear as obstacles in Super Mario Odyssey. They have a similar appearance and behavior to the Spike Bar obstacles seen in other games, however, they appear to be made out of stone or rock instead of metal and have a base made out of Moon Rock. They come in different lengths and some have more than one set on a base. Some Moonsnakes are also able to move back and forth in a set path. They appear in the Seaside Kingdom, Moon Kingdom, Dark Side, and Darker Side. They cannot be defeated by any means.
