Ruggers were cute, fluffy rodents native to the forest moon of Endor. They lived in the planetoid's grassy plains (yellow-furred) or high in the trees (greenish white-furred), eating nuts and berries, and hibernating in the winter. They had sharp front incisors and suction-like foot pads among their adaptations. Ruggers were favored prey of Yuzzum and temptors. Domestic ruggers were kept as pets by the wealthy on Coruscant and had white fur.
