Gargan Roo

Gargan Roo is an ancient transport network used on the Mist Continent, of the world Gaia, in Final Fantasy IX.

Gargan Roo itself is a network of roots from the huge Iifa tree, which flow through underground tunnels. The passengers ride in a carriage that hangs from the back of a giant ant, called the Gargant. It is called by feeding it flowers that look like large dandilions.

The Gargant can be spooked however by many of the monsters spawned by the mist underground, such as large snake type lizards.

There is another Gargant tunnel called Fossil Roo, which transports people to the Outer Continent.
