Skeleton Dome

Skeleton Dome is the sixth level of Sonic and the Secret Rings. However, this world has "snow" at the beginning instead of being placed in the chambers. Skeleton Dome is also home to the legendary King Solomon, a skeleton king. This world also features skeleton warriors, animal bones and two-sided axes.

Appearance
The level starts somewhere outside the dome where Shahra mistakes falling bone dust for snow. After a while you enter cavern with bone walkways leading to a palace. You then enter an arena, which also appears in acts as a circuit. At the end of Act 1, you enter the throne room where King Solomon sits. There will even be a 3D model of his head, though it is difficult to see.

Trivia

 * In one of the Rampage! missions, Sonic says "I guess that's why they call it the skeleton dome", after Shara calls the arena huge.
 * Several areas in the level have a skull with glowing red eyes that transports you to another area.
 * In Act 1, there is a secret path to an area where you run along the backbone of a serpent. This path lets you get a Gold medal due to saving time.
