Volcano Bloon is a bloon that appears in Round 35. This is very difficult to pop, because it's imune to both fire and sharp objects. The only way to pop this is to freeze. Freezing destroys it instantly, even without Snap Freeze. Arctic Wind makes slower, but does not pop it. This bloon has the speed of a Green Bloon. When popped, releases 2 Orange Bloons (my version). A Volcano Bloon can be glued, but Corrosive Glue, Bloon Dissolver and Bloon Liquifier can't pop it.
- This is the only bloon can be popped by an Ice Tower without Snap Freeze.
