Fossil Roo is a network of roots from the huge Iifa Tree, which flow through underground tunnels. The passengers ride holding onto the back of a giant mole-cricket-like insect, called the Gargant. It is called by feeding it flowers that look like large dandilions. The Gargant's routes may be altered by various switches along the path, which open up water valves across roots that deter the Gargant.
