Fossil Roo is a tunnel that connects the Mist Continent with the Outer Continent. It is an ancient transport network in Final Fantasy IX. Fossil Roo is a network of roots from the huge Iifa Tree, which flows through underground tunnels. The passengers ride holding onto the back of a giant mole-cricket-like insect called the Gargant. It is beckoned by feeding it flowers that look like large dandelions. The Gargant's routes may be altered by various switches along the path, which open up water valves across roots that deter the Gargant.
