Wonder Island (ワンダーアイランド), also called Strange Island, is an island shaped like a question mark that is located a distance from Gengoro Island.
Wonder Island is the primary setting to Akira Toriyama's first published manga, Wonder Island. In Dr. Slump, Senbei Norimaki, Arale Norimaki, and Gatchan travel to this island in order to obtain a tear from the Ogre-king Gyaska to make the Fall-Go-Boom Love Potion for Senbei.
Many creatures mostly based on Japanese fairy tails live there. Wonder Island is notably the home to P-Man, a fairy, flying fish, monkeys, a hang-gliding gorilla, a witch, vampires, dinosaurs, an angel, frogs, and a dragon. King Ghidorah, Little Red Riding Hood, Momotaro, and Kintarō are also seen there.
