Glass Bloon

"Bloons made of glass. What madness! They're immune to your tech weapons, Super Monkey, but my research can help."

- Dr. Monkey

The  is a bloon that appears in Bloons Super Monkey 2 (and its mobile port). It is a bloon made of glass, as its name implies. This bloon is immune to the upgrades in the tech path (including lasers, plasma, whips, etc.) unless research is used. It takes up to 14 shots to pop the entire bloon, with fewer pops releasing additional bloons. This bloon spawned may be anything up to and including Zebra Bloons, although Lead Bloons will not be spawned.

In the mobile version of the game, the Glass Bloon is also immune to Storm weapons, but only the Arm weapons. When popped, it releases 2 Zebra Bloons instead, thus making it the more powerful version of the Rainbow Bloon due to its added immunity.

 * [high-pitched glass hit]

Trivia

 * It is hard to tell the difference between a Shielded Glass Bloon and a normal Glass Bloon, especially if it is in a group of Glass Bloons. The difference can be distinguished from the lightning bolt in the center and the faint white outline.
 * In BTD6, the new Purple Bloon succeeds the Glass Bloon's role, with the addition of being immune to magic and fire attacks, while the immunity to plasma is retained, but is weaker and contains two Pink Bloons.
