Planet Secco is a planet located nearby to Sonic's homeworld. It is the first planet the characters visit on their way to collect the seven Chaos Emeralds.
The planet is covered in primarily sand and water. However, the abundance of water seems to be caused by the actions of the Metarex, as the planet guide Sonic had read depicted the planet as being barren.
The inhabitants of the island have no known name, but they heavily resemble elves.
On arrival, Sonic and Chris use submarines to explore the waters of the planets, in search of the Emerald. Meanwhile, Knuckles searches the land, digging rapidly with his shovel claws.
Sonic and Chris eventually locate a Metarex base.
