Spawner Bloons

Spawner Bloons can spawn a bloon that's 2 ranks lower than itself every 2 seconds. Like Camo Bloons and Regrowth Bloons, it's more of an effect so any bloon can be a Spawner Bloon (though it's useless for Red and Blue Bloons) In appearance, it has a black "+" symbol on it, but Black Bloons have a white one instead.
