Observer Bloon

"Not quite big enough to qualify as a MOAB-Class, a bit too big for a regular Bloon, and unusually passive for a Bloon of any kind. The monkey scientists are honestly unsure where on earth to put this thing in their hierarchy!"

The Observer Bloon is a large Bloon type exclusive to tracks with multiple paths, and appears randomly after Round 20 on tracks that qualify. A large, circular Bloon stretching the boundary between regular Bloons and the large MOAB-Class Bloons, the Observer Bloon inherits the slowness of the MOABs and the frailty of the regular Bloons. Thus, it does its best to stay back on the path and it cannot take lives directly.

Statistics

 * Speed is between Red and Blue Bloon.
 * Forty hitpoints. No defenses.
 * Does not take lives as it does not go for the exit.
 * Spawns one Ceramic Bloon on being popped.

Behavior
The Observer Bloon may not be able to do much by itself, but it is smarter than most other Bloons. Before spawning, a check is run to see which path has the least tower coverage. The Observer then spawns on the path with the least coverage, advances around one-third of the way, then performs its Forward Outpost ability. After it has completed this, the Observer then retreats back out the entrance.

Ability
Forward Outpost - The Observer Bloon moves off the path slightly, then appears to radio in for support (similar to the activated ability of the Sniper Monkey). A wave of bloons equivalent to five percent of the wave's total Red Bloon Equivalent will spawn nearby the Observer and then make their way down the path as normal. Typically, the spawned Bloons will be the highest ranked Bloon in the round proper until MOAB-Class Bloons begin appearing, upon which they will stop at Ceramic Bloons. This ability is only used once.
