 * Nandi Bear - a species of large elephant-sized bears with a tawny furry coat, large chocolate-colored spots, a short tail, and mostly bipedal with short forearms. Females often have scars from carrying their young on their backs. Unlike the legendary Nandi bear, that was very dangerous and craved for human brains, the giant Nandi bears are always vegetarians, since they live on fruits and vegetables in the Western Savannah, although they will attack if they are threataned, and can and will eat bugs, eggs, fish, and carrion.
 * Scavenger Deer - Elk-like Deer with native to Northeastern Alpine and Northern Taiga that have a taste for corpses.
 * Domesticated Scavenger Deer - Scavenger Deer that have been tamed by the Alamases of the Northeastern Alpine for security and transportation purposes. Although they are much friendlier then their wild counterparts, they will attack if provoked.
 * Lava Salamander - Large crocodile-sized salamanders with acidic skin that can burn every village in Arco Iris and have a poisonous bite like Gila monsters and shrews.
 * Porculion - A big lion with large sharp quills for a mane and on its back that stabs anyone who gets too close to its cave where it lives in the Southeastern forest.
 * Skunk Bear - Large black bears with the tail and the black and white pattern of a spotted skunk that spray foul odor on anyone who gets into its home in the Northern Taiga.

 * Wandering Pigs - Brown wild boars that travel the Western Savannah like bison across the Great Plains or Wildebeests across the African Plains.
 * Iguana Edaphosauromimus - large iguanas that get their name from the the large sail on it's back that give an appearance similar to that of a Permian reptile called Edaphosaurus. They are common prey items of many predators throughout the western and eastern hemisphere of Arco Iris.
 * Peninsula Crocodiles - giant crocodiles that can be green, brown, pale yellow, or a combination of all three. They are so big, they can be mistaken for peninsulas along the riverbanks and coasts of the Eastern Jungle, Southern Mangroves, and Western Savannah where they live.
 * Long-necked Hippo Beast - a large plesiosaur-like hippo that swims entirely in a very large lake in the Eastern Jungle, probably a way for the Star Girls to ride on.
 * The Water Phoenix - a bird that is long-lived when reborn by water waves, unlike the legendary phoenix, that was reborn in ashes by a fire.
