Underwater dweller A species of amphibious , sentient humanoids was characterized by green , scaly skin and yellow fins . Some members of the species were short and plump , while others were tall and brawny . Many of the humanoids inhabited the Underwater Kingdom , located below the surface of Sunshine Lake on the Forest Moon of Endor . Most of that population lived in large caves , where they cultivated their main source of sustenance , known as food pearl s , with the help of the light from a large red pearl . Other members of the species on Endor terrorized their brethren by raiding them for this commodity . In 3 ABY , an Underwater Kingdom subject named Squik rescued the Ewoks Wicket W . Warrick and Teebo after a creature known as a devil serpent attacked them . Squik took the Ewoks to the Underwater Kingdom . A tyrant named Orcon assailed the settlement and made off with their red pearl . Squik and the Ewoks voyaged to his stronghold to recover it , but the gem was destroyed in a skirmish there . However , Teebo gave the underwater dwellers a blue pearl that was even more powerful than its predecessor . Biology and appearance . Living in subaquatic settlements , one sentient species was adapted to life in fresh water . Except for a yellow tail , their bodies were covered in green scales and featured a musculature and anatomy similar to that of other humanoid species . Their faces had white eyes , small depressions where the nose of other beings might be , and expressive brows . Yellow fins grew in several locations along the body : the back of the head , the sides of the cheeks , the insides of the forearms , the length of the spine , and the tip of the tail . They had three clawed digits on each webbed hand and foot . Members of the species could breathe and speak both in and out of water , and they were strong swimmers , able to withstand powerful currents . The species came in two major variations that differed primarily in size : one group stood about a meter tall on average , while the other was almost twice that height . The shorter group were pudgy , with limbs relatively short in proportion to the body , whereas the taller group were muscular , with humanoid dimensions similar to Humans and other species . Both groups had strong jaws capable of eating hard pearls , but the taller members of the species also made use of sharp teeth . Whereas the shorter underwater dwellers had green bellies that matched the rest of their coloration , the taller variants had yellow stomachs that displayed a pattern of deep striations . Society and culture . A group of underwater dwellers lived in the Underwater Kingdom , a polity deep beneath the surface of Sunshine Lake on the Forest Moon of Endor . Their main settlement was a large grotto accessible only through an underwater opening . Meanwhile , a bigger member of the species , Orcon , lived alone in his personal stronghold , a cave within an underwater mountain . Although Orcon ' s domain was barren , the cave where his smaller brethren lived was littered with shiny , yellow food pearl s , which were carved up with knives and eaten as the main source of nourishment . The light emitted by a large , red pearl fostered the growth of these foodstuffs until it was replaced by an even more potent blue pearl in 3 ABY . The underwater dwellers considered these luminescent pearls their most important cultural possession and kept them hidden in a large shell . Endor ' s underwater dwellers had access to simple technology such as knives , net s , and trident s . They tamed lake creatures such as devil serpent s and water wallock s as mounts and attack beasts , and even knew how to summon these creatures by blowing through shells . Orcon had a trident with which he controlled his personal devil serpent . The denizens of the Underwater Kingdom were vulnerable to raiders . The smaller underwater dwellers , for example , had to contend with Orcon , who demanded tribute in the form of food pearls . Orcon was capable of ignoring the pleas of his victims and of showing no remorse when he took all of their food pearls and left his cousins to starve . Although their aquatic lifestyle kept them from encountering terrestrial sentient species with any regularity , the underwater dwellers were generally welcoming and hospitable to such strangers , whom they called " surface dwellers . " Food pearls were a common gift offered to such guests . Other members of the species , however , demanded that strangers treat them with the utmost respect and grew irked at perceived slights . Endor ' s underwater dwellers were able to speak and comprehend Ewokese . History . The underwater dwellers of Endor established the Underwater Kingdom under the surface of Sunshine Lake . They learned to cultivate food pearls , and chose the lake ' s submarine grottos as their homes . They tamed the native creatures of the lake as mounts and beasts of burden . At some point , a larger , more aggressive underwater dweller named Orcon took up residence in a large , underwater stronghold . He relied on his smaller brethren for food pearls and survived by raiding their grottos on his personal devil serpent . The smaller underwater dwellers quickly learned that giving in to his demands was a sure way to make him leave , and they grew inured to his despoliations . In 3 ABY , an underwater dweller named Squik rescued two surface dwellers from drowning in the lake and carried them into his people ' s underwater lair . The underwater dwellers welcomed the strangers , Ewoks named Teebo and Wicket , and showed them around their home . However , the tour was interrupted when Orcon appeared astride his devil serpent and demanded food pearls . Although the smaller underwater dwellers complied , Orcon demanded the remainder of their stores . The Ewoks pleaded for him to leave , but he took umbrage and commanded his devil serpent to open fire with its energy beams . The resulting fracas unearthed the red pearl , and Orcon absconded with this new prize . The smaller underwater dwellers despaired that the loss of the pearl would spell their doom , but Wicket formulated a plan to recover the item . He and Teebo would need to travel underwater to Orcon ' s stronghold , so Wicket fashioned makeshift helmets for himself and Teebo from bubble plant s , and Squik summoned two water wallocks for the Ewoks to ride . Squik led the way to Orcon ' s lair , where the trio sneaked past the devil serpent and entered . The Ewoks attacked Orcon and wrestled the red pearl away , but the brigand summoned his attack beast and commanded it to blast the interlopers . Squik grabbed the red pearl and created a diversion as Wicket and Teebo swung by on vines and swiped the trident Orcon used to command the beast . The ploy worked , and Wicket used the three - pronged weapon to order the serpent to attack its former master . Orcon fled , but the red pearl was destroyed in the commotion . Squik despaired that the loss of the pearl would truly spell the end of his people . However , back at the Underwater Kingdom ' s main grotto , Teebo presented a blue pearl he had found to his new allies to cheer them up . To everyone ' s surprise , it had an even more powerful effect over the food pearls than its red counterpart had previously manifested . Behind the scenes . This unnamed amphibious species appears in " , " a Marvel comic book written by David Manak and illustrated by Warren Kremer . The story leaves the real name of the species a mystery and reveals only scant information about their society . The comic also fails to establish why some underwater dwellers are short and chubby while others are tall and muscular . The variation may represent juveniles and adults , two distinct races , or even two different species . Similarly , no information is provided about the underwater dwellers ' origins . Other sources suggest that they did not evolve on Endor and are instead from another planet . For example , " Geonosis and the Outer Rim Worlds " lists only Ewoks and Yuzzums as native to the Forest Moon . Similarly , " Castaways of Endor " adds only Duloks to this company . Nevertheless , these two works , along with " Endor and the Moddell Sector , " provide a rationale for the moon ' s myriad other sentients : such beings are offworlders who crash landed there after falling prey to Endor ' s massive gravity shadow and large screen of space detritus . Nevertheless , no source explicitly describes the underwater dwellers as hailing from another planet , so they cannot be ruled out entirely as natives of the moon .
