Helium Bloon (Shiverpeace)

"This bloon is so full of itself that it needs a jar to prevent itself from floating off into space. Beware; the bloon's jar is made of glass, bulletproof, fireproof, magicproof, can't be scratched by weaker sharp projectiles such as darts, isn't slowed by glue, and apparently full of anti-freeze."

- Pioneer Original

The Helium Bloon is a bloon hat may or may not exist in BTDI. When fully popped, it releases two Zebra Bloons. Like the Ceramic Bloon and the Mosaic Bloon, it is not slowed by glue (though only with its glass jar). It is initially merely as fast as a Blue Bloon; however, after its jar is destroyed, it moves as fast as a Pink Bloon.

Its jar is also immune to explosions, freezing, magic, light and lasers, weaker sharp projectiles including bullets, and fire, requiring methods such as: The jar can take 2 hits before being destroyed. After its jar is destroyed, it loses these immunities but gains speed.
 * crushing or smashing attacks or blunt projectiles (e.g. Pat Fusty, Juggernaut, Boomerang Thrower, Razor Rotors, Miner Monkey, Tribal Turtle's coconuts, etc.)
 * corrosive attacks (e.g. Corrosive Glue Gunner, Alchemist, etc.)
 * electricity (e.g. Heart of Thunder, Cuckoo's zaps, etc.)
 * other miscellaneous methods (e.g. bloontonium weapons, plasma attacks, Monkey Intelligence Bureau, most tier 5 or 6 upgrades, and certain upgrades like White Hot Spikes, Flash Bomb, and Heavy Bombs, etc.).

Strategy
This bloon has a stupidly wide range of immunities that, without the correct defense, can effectively end the game.

Towers that have extra effectiveness against Ceramic Bloons usually can bypass the Helium Bloon's immunities, such as Juggernauts and Ultra-Juggernauts.

This bloon is not slowed by glue, so non-Corrosive Glue Gunners are not recommended against this bloon.

Otherwise, one could think of this as a stronger Rainbow Bloon that has lots of immunities, 2 extra layers, and increased speed after its extra layers are destroyed.

And obviously, this text was most definitely not copied from Mosaic Bloon's.

Trivia

 * It shall not be explained how a single boomerang can smash a jar while indefinite amounts of bullets can't.
 * This bloon is inspired by:
 * Ceramic Bloon's multiple layers
 * Ceramic Bloon's immunity to being slowed by glue
 * Ceramic Bloon's immunity to magic in Bloons Super Monkey 2
 * Glass Bloon's immunity to light and laser-based attacks in Bloons Super Monkey 2
 * Black Bloon's immunity to bombs and explosions
 * White Bloon's immunity to freezing
 * Orange Bloon's (Purple Bloon's in BTD6) immunity to fire
 * Lead Bloon's immunity to sharp projectiles and apparently non-Full Metal Jacket Sniper Monkeys
