Zandor Rocker The Zandor Rockers were a species of sentient beings who looked like rocks with legs and faces . By hiding on the ground , legs retracted , eyes and mouth closed , they could pass for mundane stones . The Rockers could run quickly on their legs or burrow rapidly through the ground . Zandor Rockers lived on the Forest Moon of Endor in the land for which they were named . At one point , an Ogre named Gantu began raiding their territory for sunnydew flower s . Without the plants ' nectar to sustain them , Zandor ' s flora died out and left the region barren . When two Ewoks ventured into Zandor in 3 ABY searching for the Ogre , the Rockers aided them in finding and fighting the raider . Their efforts helped chase off Gantu and restore the land to fertility . Biology and appearance . Zandor Rockers were a species of small sentient beings who looked like stones . Although their shape varied from one individual to the next , most had a wide , flat base that rounded out to a dome - like top . They stood less than a meter tall . Two short , thin legs with narrow feet jutted out from under the body ' s base and permitted the Rocker to run as quickly as an Ewok . Rockers could also spin their bodies so rapidly that their momentum carried them into the ground like a drill and created a tunnel large enough for an Ewok to crawl through , but much too narrow for an Ogre to follow . However , that left them dizzy and disoriented . A Rocker ' s body and head formed one unit , although members of the species referred to this portion of their anatomy as a " head . " The face — two small eyes , a wide brow , and a gaping mouth — was plastic enough to express a wide range of emotions . They could speak even with their mouths closed . The entire body was gray , down to the eyes and inside of the mouth . Some Rockers had a white coating atop the head that resembled hair . Rockers felt pain like other sentient beings . They could use their entire body as a weapon against larger creatures , even Ogres . Simply jumping on their enemy with their full weight could be quite painful to the target . Society and culture . Several Rockers lived in the Zandor region of the Forest Moon of Endor . There , they huddled in groups and lay about on the ground with their eyes and mouths closed and legs held underneath the body , camouflaged as mundane stones . Despite their mineral appearance , the Zandor Rockers took offense to being treated like ordinary stones ; throwing them or sitting on them were particularly objectionable . They also refrained from throwing pebbles , as the confusion between Rockers and rocks could prove dangerous . Despite these hang - ups , the Zandor Rockers were friendly to outsiders , and even spoke Ewokese . They assumed strangers were amicable unless they proved themselves a threat . They held a grudge against the Ogre Gantu , for example , for his role in the despoliation of their territory . History . The Zandor Rockers established their home in the Zandor region of the Forest Moon of Endor . There , they lived in harmony with the region ' s sunnydew flower s , plants that created sunnydew nectar and sustained the growth of the rest of Zandor ' s plant life . However , an Ogre named Gantu discovered the nectar . He began raiding Rocker territory for the flowers , eventually removing all but one blossom from the area and using the nectar to light his cave . Without the nectar to sustain them , Zandor ' s plants died , and the land became a desert . In 3 ABY , a pair of Ewoks , Teebo and Wicket W . Warrick , entered Zandor Rocker territory and took a rest among a camouflaged group of the beings . After some initial faux pas and ruffled feathers , both parties realized that they were mutual enemies of the Ogre Gantu , who had raided the Ewoks ' village in the past . The Ewoks asked to be taken to Gantu ' s cave , and a Rocker led the way . Shortly after they arrived , Gantu returned , and a fight broke out over the nectar and the bridge crystal , an item that , when held to the sun , created the Rainbow Bridge by which the Ewoks and Gantu could travel to one another ' s territory . In the commotion , Gantu spilled the nectar on himself , causing his body to glow . He ran off in joy , and new sunnydew flowers sprouted from some nectar that had spilled to the ground . The Rockers urged the Ewoks to return home before the Ogre returned . The bridge crystal had been destroyed in the confrontation with the Ogre , making the Rainbow Bridge impossible , so the Rockers burrowed under the gorge to create a tunnel through which the Ewoks could pass instead . Vowing to visit again , the Ewoks departed . With the return of the sunnydew flowers , Zandor returned to its previous fecundity . Behind the scenes . The Zandor Rockers were created by writer Dave Manak and artist Warren Kremer for " , " a comic book published by Marvel Comics in May 1985 . Later sources suggest that the Rockers likely originated on another planet and arrived on the Forest Moon as part of a shipwreck . " Geonosis and the Outer Rim Worlds , " for example , lists only Ewoks and Yuzzums as native to Endor , while " Castaways of Endor " lists natives as Ewoks , Yuzzums , and Duloks . These sources and the article " Endor and the Moddell Sector " describe Endor ' s numerous other sentient inhabitants as survivors of crash landings instigated by hazards such as Endor ' s gravity shadow and a nearby cloak of debris and detritus . Still , no source explicitly names another homeworld for the Rockers . The Zandor Rockers may have been mineral - based organisms , although their biology is never conclusively mentioned in the story in which they appear . Several mineral - based individuals lived on Endor , such as Mount Sorrow , the Black Cavern , and the Rock Wizard .
