Horse

Horses do not exist in RuneScape and are considered to be mythical creatures by the inhabitants of Gielinor. However, there are many references to horses in the game, and a few in the novel Return to Canifis:
 * Toy horsies, which were part of an April Fools' joke in 2004. Many players had requested horses for RuneScape, and the update poked fun at them
 * A painted kiteshield and banner with a horse crest on it. Players must have a toy horsey in their inventory.
 * Before if players travelled between Shilo Village and Brimhaven using the Shilo Village cart system, you would get the message: You jump into the cart and the driver urges the horses on. You take a taxing journey through the jungle to Brimhaven/Shilo Village. Even though horses are mentioned, they were never seen.
 * The carts outside Ardougne's south bank and the farm in Morytania have examine text that reads "One horsepower; wooden suspension: a beauty." Implying it is probably driven by a horse.
 * In Horvik's shop, there are horseshoes on his wall. When examined, they say these would make fine shoes for...um...unicorns.
 * The Flying Horse Inn in East Ardougne.
 * When summoning the fairy dragon K'klik, you may choose to ask him for a horse to which he replies that there are no horses in RuneScape.
 * The half-man, half-horse Centaurs, and their examine information: "Horseplay".
 * Unicorns, the horse-like creatures that are common in RuneScape, though mythical in the real world. The examine text for a Unicorn is in fact "horse with a horn".
 * If you ask Sylas about things he has found during the Grim Tales quest, he will say that he once found a unicorn without a horn. The player will be amazed.
 * Horses, a colour changing chicken seen during Halloween 2011.
 * Horses are briefly mentioned in the Zarosian lore 'Twice Burnt'.
 * A Ports Update says: Your ship (...) has passed an island where natives ride on strange beasts like hornless unicorns. This suggests that horses exist in the Eastern Lands.
