Hooroglyphs

Hooroglyphs are ancient letters found in Mario & Luigi: Superstar Saga. These ancient letters appeared in the background of Hoohoo Village, Hoohoo Mountain, and Guffawha Ruins (the last of which is out-of-place as it is strangely not an area seemingly controlled by the "Hoohoo"-type peoples). Whether the language is still used or not is unknown, although a Hoohooligan mentioned it was used by the Hoohoo Civilization and chronicled the countless jokes developed by it. Hooroglyphs mostly look like a mixture of lines and dots that come together to form the picture of a laughing person. They serve no apparent function to Mario and Luigi's quest. Hoohooros, guardian of Hoohoo Mountain, hides behind pillars engraved with Hooroglyphs during battle.

Trivia

 * The name of the Hooroglyphs is derived from the ancient Egyptian language of hieroglyphics, and it also includes the "Hoohoo" laugh title used by areas such as Hoohoo Mountain.
