Gigganda are large, mountain-dwelling mammals covered in scales and thick patches of fur, which protect them from both freezing winters and boiling summers. They patrol their mountain dutifully, keeping an inventory of which creatures are on the island and where. Those a gigganda deem "unworthy" will have their path physically blocked and be bullied off the mountain by the large beast. Prolonged exposure to giggandas' deepest growls can cause serious health problems and shaky bones syndrome.
