Crystal Spirit Bloon

The Crystal Spirit Bloon is the mini-boss of Recoverer of the Stolen Crystal, appearing at Round 42 (since 42.5 is the half of 85). It has 21500 HP without it's crystal and 25000 HP with it's crystal, and has 35000 HP in it's second form without the crystal, and 40000 HP with it's crystal. It has it's own unique spirit ability, called 'Stealth and Spirit'.

First Form
It has 21500 HP normally, but with the crystal, 25000 H. Of course the crystal has to be recovered first. This form has 4 abilities, not counting it's spirit ability.

Invisibility: Becomes camo for five seconds. However, it's a special version of the Camo Property, only made for this bloon and CAM 5 - REG 4! The bloon can't be affected by any attack unless an attack randomly pierces through it.

Camo Regen Rush: Spawns 10 Camo Regen clones of itself. Of course, the clones are weaker....

Crystalline Action: It's crystal takes action to a random tower, slowing it by 10% for 5 seconds, as well as dealing 10 HP to it.

Crystal Missile: Sends a crystal powered missile to 3 towers. These missiles are piercing, and deal 25 HP to any tower hit from the missile. The missile later gets destroyed into pieces, dealing 5 HP to any tower it touches!

Spirit Ability: Stealth and Spirit: The bloon gets stealthy, unable to be hit by most towers (except those Tier 3 or 4 towers costing more than $20000), then uses it's ultimate spirit ability: Monkey Destroyer. The crystal attacks your monkey towers, killing them and replacing them with empty spaces. Then it explodes, taking away several lives. The bloon won't be popped, however! Then your monkeys are replaced with different monkeys, however, the types are the same! Unfortunately, your monkeys have half their maximum health! Don't worry, this ability only takes action when it has got 5000 or 1000 HP left (it's second attempt will most likely be a terrifying failure!)! The mechanical towers will change place too...
