Orange Bloon (WolfiZee)

The Orange Bloon is a Bloon Conception for the Bloons Tower Defense 6: More Bloons Expansion, first appearing on round 44. Though it only has the RBE of a Red Bloon, it has the ability of making non-MOAB-class Bloons in a small radius (roughly that of an unupgraded Tack Shooter) invulnerable to damage (Though they still can be pierced through, it just won't pop them). The Orange Bloon's ability also cannot effect other Orange Bloons.

Strategy
When dealing with Orange Bloons, it is best to bring high-pierce towers to take care of it, as other towers' attacks will be blocked by the Bloons surrounding it, now made invulnerable. For this reason, it would be best to use a 3-x-x or 4-x-x Boomerang Monkey to make quick work of the Orange Bloon, as it will ricochet off of the Bloons it makes invulnerable to easily pop them.
