- Volcano is an unlockable level that can be purchased for 45,000 Battle Tokens.
- This level is similar to Club Caldera, minus the resort buildings. The cruise ship is still present.
- This level has just the two dive-attack craters within the volcano.
- Besides Mini Bay Town, this is the only stage in the game that plays no role in adventure mode.
- Volcano looks very reminiscent to the volcano seen in Magmo's origin story, though this could be purely coincidental.
- This is the only level in the entire game to have an entirely geographically-based environment, with no buildings in sight.
- The level shares the same colour palette as Rosdale Canyon and Tsunopolis.
