The Calico Desert is located far to the northwest of ペリカンタウン. It is not accessible until the Bus at the バス停 has been repaired by completing the Vault bundles at the 公民館 or by purchasing the Bus Repair for 40,000g from the Joja Community Development Form.
Once repaired, パム will return to work as the Bus driver. A ticket to ride the bus to the desert costs 500g each time, although the return trip is free. Tickets can only be purchased when パム is present at the Bus (10:10 am - 5:00 pm).
The store オアシス can be located in the southwest section of the area. It is run by サンディ and sells a number of seeds not available in Pelican Town, along with an additional item that depends on the day of the week.
In the North-East part of the desert lie three pillars, at the location of one of the game's シークレット類. This is the place where you can obtain the Galaxy Sword, by holding a レインボージェム and entering the tile at the center of the pillars.
Located directly to the north of the store in the オアシス is a hill in which lies the large bones of a sand dragon. While standing near the skull of the creature, you may interact with it and a text-screen then reads "Its maw gapes at the desert sun. Even in death, it yearns for a taste."
