The '''Subterranean Worm''' is a raceof giant, strong, tentacled creatures that dwell deep in [[Onu-Wahi]] and are spoken of mainly in legends, and occasionally spotted by miners. They are blind and navigate by hearing, and are rumored to feed on [[Protodermis]]. They have lived underground since before the [[Matoran]] came to [[Mata Nui (Location)|Mata Nui]]. The one described in [[BIONICLE Chronicles 4: Tales of the Masks]] was huge, tentacled, bleach white and had no eyes. Instead, it navigated by sound, which [[Onua|Onua Nuva]] used to his advantage by creating a sound that caused it pain because of its enhancedsenses.
