Volcano is the fifth level in Rolling Sky.
- Level 5 stays in the inferno background throughout the level. It was the only level to have 1 theme before Ghost Dance when Clown Park came out. Most levels past Ghost Dance have 1 theme.
- It was the last level when Rolling Sky was first released.
- It also has the least music-y music which is very quiet in some parts, which isn't for the whole level. This part of the music is played three times. It sounds like power turning off.
- It is the other level that has the earliest gem, which is at just 1%.
- The level, surprisingly, can be beaten without gems.
