With their lumbering bodies and strangely delicate flipper appendages, these mammals seem like refugees from some bygone era. Despite their physical size, they are passive in their quest for food: using an efficient baleen (bony plates instead of teeth) feeding mechanism, they ingest the colonies of microscopic organisms that thrive in these waters. They have distinctive dual-colored hides.
Rivenese children love the Sunners, drawing pictures in adoration. They are however edible and the Rivenese hunt them with harpoons. Their generous pelts are used for rudimentary clothing and pouches.
Smaller than the wahrk, Sunners are designated the number 4 by the Moiety. There is a wooden eye hidden in a path of the jungle. Unlike other wooden eyes on Jungle Island, this is not near a shape resembling its corresponding creature (it is found below a giant sword) however the association is obvious because of its sound.
The sunners presumably became extinct upon the destruction of Riven.
