An Error is a creature in Space Funeral. They appear to be glitched and shifting squares that can appear anywhere. According to Leg Horse, they are relics from the Great Change that were formed when an object couldn’t be changed. They can be found on the river to the Blood Cavern and in a small room in the Malice Dig Site. The man next to the Error explains that people are digging up many in the mines and that he wonders what they are.
