Cloud Bloon

This bloon is a bloon that looks like a cloud. It is immune to ALL projectiles. It cannot move, so in a way, it's an aerostat. It has 1000 HP. When it moves, it releases 10 Aqua Bloons every second. Only MOAB-class bloons can push this. When it touches an aqua bloon (icy bloons also if winter scene), it gains 35 HP. If the scene is wintery, it releases frozen bloons instead of aqua bloons. Every times it spawns a bloon, it loses 35 HP. It spawns in the front & catches bloons from the back.
